Maximum execution time in phpMyadmin

For Xampp version on Windows

Add this line to xampp\phpmyadmin\config.inc.php

$cfg['ExecTimeLimit'] = 6000;

And Change xampp\php\php.ini to

post_max_size = 750M 
upload_max_filesize = 750M   
max_execution_time = 5000
max_input_time = 5000
memory_limit = 1000M

And change xampp\mysql\bin\my.ini

max_allowed_packet = 200M

I have the same error, please go to

xampp\phpMyAdmin\libraries\config.default.php

Look for : $cfg['ExecTimeLimit'] = 600;

You can change '600' to any higher value, like '6000'.

Maximum execution time in seconds is (0 for no limit).

This will fix your error.
