🔥 Why won’t Apache start in XAMPP?

One of the most searched questions is “why won’t Apache start in XAMPP?”, and the answer can have several causes. Let’s go with the most typical ones:

🔸 1. Port 80 occupied by another program

This is THE classic one. Many programs like Skype, IIS (Internet Information Services) or even other servers occupy port 80, which is the one Apache needs to work.

  • Open the XAMPP Control Panel as administrator.
  • Click on the Config button for Apache > httpd.conf.
  • Find the line: Listen 80 → change it to Listen 8080.
  • Also modify: ServerName localhost:80 → ServerName localhost:8080.
  • Save, close and restart Apache.

And that’s it, now you know how to fix the error of Apache not starting in XAMPP. 😉

💾 Why won’t MySQL start in XAMPP?

Another super frequent query is: “how to fix the error of MySQL not starting in XAMPP?”

This happens a lot when:

🔸 1. MySQL is already running from another installation (like Workbench or WAMP)

✅ Quick fix:

  • In the XAMPP panel, click on Config for MySQL > my.ini.
  • Change this line: port=3306 to port=3307 (or any free port).
  • Restart the service. Sometimes that’s all it takes.

🔸 2. Corrupted files in the database

Sometimes XAMPP fails because it was closed improperly, and MySQL can’t bring up the database.

✅ Fix:

  • Close XAMPP.
  • Go to the folder xampp/mysql/data.
  • Rename your database (mydb → mydb_old).
  • Restore a backup if you have one or reinstall XAMPP if it won’t start.

With that you should avoid the common problem of “MySQL won’t start in XAMPP”.

⚠️ What to do when XAMPP gives a port 80 error?

Another little gem that brings headaches: the port 80 error in XAMPP.

  • Type “Services” in the Windows search bar.
  • Look for “World Wide Web Publishing Service” (it’s IIS).
  • Right click > “Stop”.
  • Then open XAMPP and try to start Apache.

That answers it right away: “how to free up occupied ports in Windows so XAMPP works?”
