Page builder menu

hi guys I have a problem with page builder menu in admin panel... when I click on it no blocks appears on the page... just writing loading... and nothing more... please help to solve that problem

I just ran into the same problem..caused by operator error (read me)  Somehow I ended up getting some inline .css into functions.php file. Have no idea though how I managed to do that. Once I removed it all was fine. So you might want to check that file probably located at: yoursite/templates/tmpl_uni/scripts/funtions.php If you have somehow altered that file it may be the cause.
