Help! Can anybody help with this. I have no idea what it means or how to fix it? I am using joomla 3.9.6 and virtuemart 3.4 versions. I am in the process of loading the product categories to be displayed on the left Catalogue menu side and then I got this error message, I have also noticed that I cant get the categories to "drop down" under the main heading "Skin Care" on the Catalogue menu. can anybody shed some light.
tks
