xaamp MySql server wont start

Question

I have been using this for a few days with no issue but yesterday the mysql server refused to start. I have rebooted everything and it is still doing the same thing. Here is part of the log file. Please let me know how to get it back up and running and why it is doing this? This is windows 10 operating systems. Also, Apache server still starts fine.

Answer 1

Copy from xampp/mysql/backup folder and paste in xampp/mysql/data folder except ibdata1 file.

If you replace ibdata1 file from xampp/mysql/data then some database you will get error table does not exist.
