In front end view I get "No valid layout found for Categories!" [Solved]

[fstltna]

I have a "List All Categories" menu item but when you try and browse the categories you get the "No valid layout found for Categories!" message. I'm using joomla 3.10.3 and jdownloads 3.9.8.1. This is happening on all my sites right now...

Hi
I looked at your Amiga site and saw the message.
Which version of php are you using?
Will also send you a PM (Personal Message)
