I was trying to export the database from phpmyadmin and this error is showing up
"Fatal error: 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 380 and defined in C:\xampp\phpMyAdmin\libraries\classes\Export.php:270 Stack trace: #0 C:\xampp\phpMyAdmin\export.php(380): PhpMyAdmin\Export->getFilenameAndMimetype('database', '', Object(PhpMyAdmin\Plugins\Export\ExportSql), '', NULL) #1 {main} thrown in C:\xampp\phpMyAdmin\libraries\classes\Export.php on line 270"
And i tried to remove the cookies of phpmyadmin from the browser but this is not helping. This is only happening in moodle database other databases exporting fine. So how can i resolve this.
