Module Assignment Dropdown is blank

-- HikaShop version -- : 4.4.3
-- Joomla version -- : 3.9.27
-- Browser(s) name and version -- : All
-- Error-message(debug-mod must be tuned on) -- : Menu Assignment

I am trying to configure which pages the shopping cart is displayed on and it is currently set to all. I want to modify that but when I click on the Module Assignment button that says "On all pages" the box is blank.

Toggle Selection, Clear Selection and Select All do not work. Click on them and there is no response.

User creds have been emailed.

Further to the initial post, I can't select / deselect particular menus. It's either on every page, or no pages.

this one has been resolved - I chose another admin template and everything is now accessible

Hi,

Yes, the backend of HikaShop has been made to work with the CSS and Javascript of the isis template.
It might work with other templates but it's likely to have conflicts here and there the further appart from isis your backend template is.
I would normally recommend to stick to the default template for the backend.
