Sorry to bother you again Chuck but this is not working for me.
When I use the code above it stops the whole of the recent comments section from showing. I checked over the code and noticed that elsewhere on here you have recommended using
Content visible to verified customers only.
the difference being the inverted commas around the cat, so I tried that as well. Again I got the same results.
Finally, to be absolutely sure, I tried it with a different cat (as the one I want to block is currently not open) but again I had the same issues.
I don't know what I am missing but I would appreciate any advice.
