• And more tips to keep your WordPress site in good shape.
Let’s get started.
Fix broken themes and plugins
Themes and plugins are a major cause of problems in WordPress. If a plugin has an error, it can damage the site’s functionality or even cause other problems.
To troubleshoot issues with themes and plugins:
• Temporarily deactivate plugins one by one until you identify which one is causing problems.
• Update plugins to the latest version. Sometimes an update fixes errors.
• Uninstall and reinstall the plugin or theme.
• Restore a backup of the theme or a previous version if available.
• Contact the plugin developer for support and possible solutions.
If none of this helps, you may need to switch to another theme or plugin.
Repair the database
Common problems:
• Error connecting to the database
• Pages showing “Error establishing a database connection”
• Failing WordPress backups
To repair the WordPress database, you can:
• Run the MySQL “CHECK TABLE” command to detect and repair damaged tables.
• Use the “wp-cli db” tool that comes included with WordPress to repair and optimize the database.
• Change the database credentials in wp-config.php if they are wrong.
• Restore a database backup.
• As a last resort, reinstall WordPress to recreate the database from scratch.
Remove malware and infections
Was your WordPress site hacked or does it have malware? These steps will help you get rid of it:
• Change all your WordPress and hosting passwords
• Update all your plugins and themes to the latest versions
• Install a security plugin like Wordfence or iThemes Security
• Scan your site with a scanner like Sucuri
• Remove malicious files and code manually by checking the FTP
• Restore a WordPress backup made before the attack
• As a last resort, reinstall WordPress from scratch
Update WordPress safely
Keeping WordPress updated is crucial for security and stability. However, updates sometimes cause problems:
• Make a full backup before updating.
• First update all plugins and themes to the latest versions.
• Temporarily deactivate non-essential plugins.
• Update WordPress from the admin panel or via the WP-CLI command line.
• Reactivate plugins one by one after the update to identify if any cause problems.
• Restore a backup if the update causes errors.
Troubleshoot 404 and 500 errors
• Error 404: Indicates that a page or file cannot be found. Common causes are broken links, changes to the site URL, damaged plugins, or an outdated link tracker.
To fix it:
- Check and update broken links
- Check the file paths in your plugins and themes
- Reset your WordPress cache
- Re-map the URLs in ‘Settings > General’
- Generate a new .htaccess if necessary
• Error 500: Indicates an internal server error. It can be caused by conflicting plugins, poorly written PHP code, broken themes, or database problems.
To fix it:
- Temporarily deactivate plugins
- Check the .htaccess file for errors
- Reinstall suspicious themes and plugins
- Update WordPress, plugins, and themes to the latest versions
- As a last resort, restore a backup.
Other ways to repair WordPress
• Reinstall WordPress: As a last resort when nothing else works, reinstalling WordPress from scratch can solve many mysterious problems. Make sure you have a full backup before proceeding.
• Change the hosting: Sometimes persistent problems can be due to the hosting. Switching to a reliable hosting provider specialized in WordPress is a good alternative.
• Hire professional support: If none of the above solutions work, it may be worth hiring a WordPress expert who can diagnose and repair the problem effectively.
That summarizes the most common ways to identify and repair problems in WordPress. The key is to proceed methodically, starting with the simplest and moving toward more drastic solutions only when necessary. With patience and the right steps, most WordPress problems can be easily resolved.
Use security and repair plugins
Installing and using the right plugins can help you prevent and fix problems in WordPress. Some good options are:
• Wordfence: This leading security plugin helps protect against malware, hacks, and spam. It also includes tools to repair WordPress, such as a security scan and a restore feature.
• iThemes Security: Another solid security option that protects against hackers, blocks incorrect login attempts, and scans the site for malware. It comes with a complete set of management and repair tools.
• WP-Optimize: Optimizes and improves WordPress performance, including database repair and optimization. It also includes a cache cleaner and an update tool.
• WP File Manager: Provides a user-friendly interface to manage files and folders on the server. Useful for manually repairing damaged themes and plugins by modifying files.
• WP Remote: Allows remote access to the WordPress admin console from any device. Useful when WordPress is broken and you can’t access the normal admin panel.
Install one or more of these plugins and use them alongside the manual techniques mentioned above. They will help prevent many problems and provide more tools to diagnose and fix whatever is needed.
Avoid future problems
After solving a problem, make sure to take preventive measures to reduce the likelihood of it happening again:
• Update WordPress, themes, and plugins regularly as soon as updates become available.
• Install and use one of the security and repair plugins mentioned above.
• Keep complete backups of WordPress in multiple locations.
• Use a strong and unique password for your WordPress installation.
• Limit admin access only to users who need it.
• Periodically check the site for broken links, suspicious PHP code, etc.
• Establish an automatic update policy for themes and plugins (if possible).
• Consider migrating to a more recent version of WordPress where feasible.
Maintaining good WordPress “hygiene” through these common practices will greatly reduce the frequency and severity of future problems that may arise.
Use wp-cli to repair WordPress
wp-cli is a powerful command-line interface for managing WordPress. It comes included with WordPress and includes many useful commands for repairing problems.
Some useful repair commands are:
• wp cache flush: Clears the WordPress cache, which can fix occasional errors.
• wp search-replace: Replaces strings in the database, useful for correcting URLs or changing domains.
• wp plugin activate / deactivate / uninstall: Manages plugins from the command line, useful for finding which one is causing problems and uninstalling it.
• wp theme activate / deactivate: Activates or deactivates themes.
• wp option update: Updates stored options to correct settings.
• wp db optimize: Optimizes the database to improve performance.
• wp db check: Checks the integrity of the database and repairs damaged tables.
• wp db repair: Repairs the database, restoring damaged tables and clearing the cache.
• wp core update: Updates WordPress safely from the command line.
wp-cli allows you to automate administrative tasks and run “repair” commands from the terminal or a script, which can fix problems more quickly and reliably.
To use wp-cli you need to:
• Install wp-cli (it usually comes included with WordPress)
• Run commands from the terminal using “wp [command]”
• Add the “–allow-root” option to allow running commands as root/administrator.
wp-cli is a great tool to use alongside the manual methods mentioned above. It allows you to run repetitive tasks in an automated way.
Use a backup
Making regular backups of WordPress is crucial to being able to repair problems effectively. Backups will give you a restore point if something goes wrong.
There are several ways to create WordPress backups:
• Backup plugin: Use a plugin like UpdraftPlus, BackupWordPress, or others. It will create automatic or on-demand backups of your entire installation.
• Manual FTP copy: Access the server via FTP and copy the entire WordPress folder. This includes files and the database.
• Export the database: From phpMyAdmin or your control panel, export the WordPress database as an SQL file. Save this along with an FTP copy.
• Use wp-cli: Run the “wp export” command to export the database. Use “wp db export” to export only the database.
• External backup program: Use tools like Backupsy, Akeeba Backup, or other third-party programs.
Make sure you have at least two backups, stored in separate locations. This will protect you against data loss.
• Restore a complete FTP backup to the server.
• Import the database SQL file.
• Set the configuration and credentials again in wp-config.php
• Reload the site in the browser to verify that it works correctly.
Having a reliable backup is always the first line of defense when problems arise in WordPress. It allows you to quickly restore your site to a known working state.
Reinstall WordPress as a last resort
Sometimes, even after trying all the above solutions, WordPress remains broken or presents unknown problems. In those cases, a complete reinstallation of WordPress is the only solution.
Before proceeding with a reinstallation, make sure you have:
• A complete backup of your current WordPress installation.
• Notes on the settings and plugins you currently use.
• A plan to restore your content after the reinstallation.
To reinstall WordPress:
- Deactivate all plugins and switch the theme to Twenty Twenty for a trouble-free experience.
- Export the database from phpMyAdmin or your control panel. Save this backup SQL file.
- Delete the existing WordPress folder from your server via FTP.
- Download the latest version of WordPress and install it in the empty folder. Follow the initial setup steps.
- Import your SQL database backup into the new WordPress installation.
- Restore your theme and plugins one by one, monitoring for problems.
- Restore your content (posts, pages, user data, etc.).
- Update URLs in the database if your site URL has changed.
This will reinstall WordPress from scratch on your server, which should fix most problems. Only reinstall as a last resort when nothing else works.
After the reinstallation, make sure to follow the best practices above to prevent problems from happening again.
