Allen:
Thanks for the response. I haven't played with any of the code but it does seem to me that something changed.
The problem occured a long time after I had 7.2.2 running.
I'm going to upload the code for the Forums Settings or Category pages first because that seems to be where the problem is.
Althoug it is possible that it's in a piece of code common to them both. I'll think I'll look at the code for them both first looking for a common piece of code.
This will probably take me a while.
