Hello!

Please someone help me. I've put a code on my wordpress customizer following a tutorial and I can't access wp-admin in wordpress anymore.

Tutorial I've followed:
Please add the given code in your wplms-customizer.php file in your wplms-customizer plugin :

addfilter('wplmscoursenavmenu','wplmscoursenav_menu');

function wplmscoursenavmenu($menuarray){

unset($menu_array['members']);

return $menu_array;

Website access works ok, but can't acess admin.
I think I need to restore .htaccess, but don't know how to locate it.

Can someone help??
Thanks
