important: Do not delete the ibdata1 file, as doing so could result in the loss of all your databases.
Instead, try using the MySQL backup folder included with XAMPP. Follow these steps:
- Rename folder
mysql/data to mysql/data_old
- Make a copy of
mysql/backup folder and name it as mysql/data
- Copy all your database folders from
mysql/data_old into mysql/data (except mysql, performance_schema, and phpmyadminfolders)
- Copy
mysql/data_old/ibdata1 file into mysql/data folder
- Start MySQL from XAMPP control panel
As noted by some users, this is an emergency solution, not a permanent fix. After recovering your data, it is strongly recommended to back it up and reinstall XAMPP. The failure is related to a malfunction in some XAMPP files, not the databases.
