xampp mysql and phpmyadmin dont work

I have fixed the issue. I copied all files in xampp/mysql/backup/ to xampp/mysql/data/.

As additional to the correct answer, you don't need to delete all the files inside xampp/mysql/data/, just replace with whatever inside xampp/mysql/backup/ will do. Cheers

I had this similar issue today and was able to solve it by:

1. Close the XAMPP control panel

2. delete the following files under /xampp/mysql/data:

   • aria_log.**1
   • aria_log_control
   • ib_logfile0
   • ib_logfile1
   • ibdata1
   • ibtmp1
   • mysqld.pid

3. AND modify the multi-master.info and delete all its content then save the file.

4. open the Xampp and run mysql again.
