When you install first-time XAMPP and import a large file in the database the that if Maximum execution time of 300 seconds exceeded will be showing this type of error in your database:
So, There’s a configuration variable within the phpMyAdmin directory that you can find in below path-
after find this below line-
“$cfg[‘ExecTimeLimit’] = 300;”
and replace below line-
“$cfg[‘ExecTimeLimit’] = 0;”
that you can set to whatever maximum execution time you need. After that your problem will be solved.
