Ubermenu is in fact unusable in the editor

Hallo there
I have here a fresh install of WP, Pro theme and the ubermenu plugin. (all latest versions)
I changed the settings for time and memory limits in the wp-config.php as recommanded here

set_time_limit(300);
define('WP_MEMORY_LIMIT', '512M');
define('WP_MAX_MEMORY_LIMIT', '1024M');

I have just 2 menus with 5 links in one and 1 link in the other.

Ubermenu lags in the backend tremendously. Once I try to edit the settings it blocks everything for a lot of time (I’m talking minutes). Sometimes only a reload makes me getting back the control over the backend resulting in loss of the previous edits. I realised this behaviour on an other website I’m managing. Here it may be because of the size and number of the menus. Hence OKAAAY… but here with this “nothing of a menu”, its not OKAY.

Thx a heap for any hint how to solve this.

Hello @VRANKOVINA,

Thanks for writing to us.

I would also suggest you please add this code to your active child theme functions.php and recheck it.

add_filter("cs_use_custom_fields_map", "__return_false");

Hope it helps
Thanks
