Internal Server Error

Hello there.

Sorry for the late response.

This is a server error, and it could be caused by a lot of things. We can’t say exactly what caused it, but you can take a look at wpDataTables/System Info, and see if there are any notices in there.

Also, you can copy the following code:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

And go to ../wp-content/plugins/wpdatatables/wpdatatables.php

On line 39 you will see this:

    if (is_admin()) {
        // Admin panel controller
        require_once(WDT_ROOT_PATH . 'controllers/wdt_admin.php');

Hit Enter on line 39, after ” { ” and add the code, so it looks like this:

    if (is_admin()) {
        ini_set('display_errors', 1);
        ini_set('display_startup_errors', 1);
        error_reporting(E_ALL);
        // Admin panel controller
        require_once(WDT_ROOT_PATH . 'controllers/wdt_admin.php');

Save the file, and then try to upload the file again. This time, it should show you the whole error, so please paste it here, remove the code you’ve added to wpdatatables.php and we’ll see what’s going on based on your response.

Kind regards
