Category Filter problems after upgrading from 3.0.18 to 3.2.1

[raydekker]

Hi Milbo, thank you very much!
Ahh ok so that's the problem, I've read some people were having these issues with multilingual sites too.
For now it's ok as I import everything using CSVI Pro (so I don't really need to have the category filter working), but eventually I'd like to get it to work again.
I can wait for the official release of VM3.2.2, it's still a functional site and I would rather not install unofficial versions just yet.
Is there maybe an easy way to get it out of "fallback mode"? I've checked my language settings but it's just set to en-GB in Joomla and VM and it's the ONLY language.

Again thanks for finding out why it stopped working, the solution is near

I've updated VM to 3.2.2 but the problem still persists... Still not able to click on the category filter dropdown in VM > Products.
Also updated to Joomla 3.7.1

Please check in your browser console for java script errors. The category filter is loaded by ajax.

I found the following line must be the issue:
TypeError: Virtuemart.loadCategoryTree is not a function[Learn More]

Empty string passed to getElementById().

mmm, but I don't know how to fix it... If Virtuemart.loadCategoryTree is NOT a function then WHAT is the correct function and where to change it (as in what file)?
It worked before, I mean the function does not just change itself... Or I'm using some custom code and this function is part of it (that could be the case as I DID make some modifications here and there). But I've never changed th function Virtuemart.loadCategoryTree...

Mmm, at least we're getting closer

Thanks for the tip Milbo, should have checked that sooner

Do you use some admin template?

No the default protostar
