[FIXED] Can't export database in phpmyadmin(xampp) : Uncaught TypeError

Issue

When I tried to export the following error showed

Uncaught TypeError: Argument 5 passed to PhpMyAdmin\Export::getFilenameAndMimetype() must be of the type string, null given, called in C:\xampp\phpMyAdmin\export.php on line 387 and defined in C:\xampp\phpMyAdmin\libraries\classes\Export.php:270 Stack trace: #0 C:\xampp\phpMyAdmin\export.php(387): PhpMyAdmin\Export->getFilenameAndMimetype('database', '', Object(PhpMyAdmin\Plugins\Export\ExportSql), '', NULL) #1 {main} thrown in C:\xampp\phpMyAdmin\libraries\classes\Export.php on line 270

Solution

uncomment max_input_vars in php.ini file and change value from 1000 to a greater value
