Appearance > Menu Incredibly Slow

The nav-menus.php is really slow in both loading and editing. I have done the usual turn everything off along with the theme. I do not have an abundance of menu items. Is there an eta or any help for a resolution on this. I can provide credentials to the site if you need to see an example.

Hi @getabsolute,

Thanks for reaching out.

If you have several menu items. Most of the time, if you have more than 20 menu items, WordPress will become slower in loading the items in Appearance > Menus . To get this resolve, you need to increase your PHP input max value and the PHP maximum execution limit. You may need to check out this links:

We would love to know if this has worked for you. Thank you.

This did not work. Although there may be a wrinkle here. Two of us are having a problem where a third coworker is not.

I tried to access your website and go to Appearance > Menus, then edit the Main(Primary Menu), the menu is not so slow, I can edit the menu without any hassle, I suggest the you will let the ubermenu load first before to attempting to edit the menu, see the video I posted on the secure note.

Hope that helps and let us know how it goes.

Thank you.
