No toolbars eg. save, save and close, etc

-- HikaShop version -- : 6.1.0
-- Joomla version -- : 6.0.0
-- PHP version -- : 8.3
-- Browser(s) name and version -- : Safari

Hi,

When accessing any of the Hickashop menu items such as categories, products listing, etc there is no toolbar for the save, save and close, cancel options plus the page is all totally messed up and showing the HTML.

I am using the latest version of Hickashop business and this is on the backend. I can therefore not create menu items for the frontend or edit current menu items.

Please help.

Many thanks.
