Fatal error: Maximum execution time of 30 seconds exceeded in C:\Program Files\Ampps\phpMyAdmin\libraries\classes\Dbi\DbiMysqli.php on line 213
find your php.ini file ( in my case C:\Program Files\Ampps\phpMyAdmin\libraries) then edit the fellowing line, before that the value is 300.
$cfg['ExecTimeLimit'] = 3000;
It may also caused by your php.ini setting, you need also change the (in my case C:\Program Files\Ampps\php-7.3\php.ini)
max_execution_time = 3000
