@xillibit let me check that tomorrow

[Ruud68]

Ok, I'm sure I tested all (except the category batch one): go figure.
Same issue as with some other controller method names: batchCategories method is the same as var in view / model. Somehow PHP / Joomla doesn't like this any more.
So renamed the method to all lowercase and now it works.

presuming this was the only modal not working, this should now be okay.

Updated this PR with new commit

[Ruud68]

Ok, just did a test and now the controller method is called okay. But now it is saying that I forgot to select a target category.

Turnout that the controller is getting the selected category from a field on the form that doesn't exist (and also didn't exist in K6.2 so this never worked?).
Anyway, did a last small change (in this PR) and should be working now.
Can you test @xillibit ?

There was two options in the categories batch one have never worked, so i have removed part in the template
