xampp mysql server not starting fix

This has happened to me on a few occasions with XAMPP, seemingly caused by stopping the MySQL server in the control panel.

This was my error log upon trying to start the MySQL server:

3:43:26 PM  [mysql] 	Attempting to start MySQL app...
3:43:26 PM  [mysql] 	Status change detected: running
3:43:28 PM  [mysql] 	Status change detected: stopped

The fix

Fixing the MySQL server not starting in XAMPP is done by reverting back the data files pre-issue.

Navigate to your XAMPP MySQL directory (C:\xampp\mysql).

Create a new folder called FIX_BACKUP.

Copy C:\xampp\mysql\backup and C:\xampp\mysql\data into C:\xampp\mysql\FIX_BACKUP.

Paste the contents of C:\xampp\mysql\backup into C:\xampp\mysql\data overwriting all the files.

Finally copy the ibdata1 file from C:\xampp\mysql\FIX_BACKUP\data into C:\xampp\mysql\data overwriting the file.

Your MySQL server should now start in the XAMPP control panel.
