after a lot of searching and playing round I disabled
"Photopost Featured Photos on Forumhome" and the forum worked again.
also the gallery version on forum home as well.
This removed the syntax error
I also found a typo in the config on the classifieds I have updated that and re did the xml thing.
As for the photo post pro navbar plugin can you please let me know how you where this is. I had to add one manually .
Cheers for looking into this for me.
