Help me out, Please

Hello,

Were you able to fix the issue? If not, you’d be able to remove the plugin settings by deleting them from the options table. First, uninstall and remove the plugin. Then, assuming you use the default table prefix (wp_), the following SQL query will delete the settings:

DELETE FROM wp_options WHERE option_name LIKE 'multiple-domain-%';

Let me know how it goes.

Hello,

It seems you don’t have direct access to your SQL database (through PHPMyAdmin or other MySQL client). No problem, you should be able to perform the query by adding the following line to the end of your theme’s functions.php file:

function delete_multiple_domain_settings() {
    global $wpdb;
    $wpdb->query("DELETE FROM wp_options WHERE option_name LIKE 'multiple-domain-%'");
}
delete_multiple_domain_settings();

Make sure you add it before the PHP closing tag (?>) if you have one at the end of that file. You can remove those lines from your functions.php file right after the issue is gone.

Some of the previous instructions still apply: make sure you disabled and uninstalled the plugin before doing that.
