the "contentheading" thing was a conflict I probably wouldn't have noticed without ionfiles, had it defined twice
Found a new cause of XHTML verification failure though, when not using a single word for a category title one of the table id's fails since spaces are not allowed. Two ways around this that I can think of:
- Couple of codelines to strip the spaces before using the title for the table id.

- using category id instead of the title for the table id
I'll take a look at it after the weekend when I'll be working on my downloads area, for now my workaround is simply to use single word category titles!
