Fatal error: Maximum execution time of 300 seconds exceeded in C:\xampp\phpMyAdmin\libraries\classes\Dbi\DbiMysqli.php

The error message you’re encountering, “Fatal error: Maximum execution time of 300 seconds exceeded,” indicates that your PHP script has exceeded the maximum execution time limit set in the PHP configuration. This typically occurs when a script takes too long to complete its execution, and PHP interrupts it to prevent server overload or resource exhaustion.

Step 1:- config.default.php

C:\xampp\phpMyAdmin\libraries

config.default.php

Step 2:-

$cfg['ExecTimeLimit'] = 0;

Restart your MySQL and Apache and go import your database.

Hopefully, It will help you …!!!!
