Here's what the tech said:
wiki thingy .. . upgraded, and active even though all is not right
-> editors are back to normal
upgraded it with the same results -- did what was recommended -- same problem, page not found
was a wTf moment .. .
-> thought and played with the language, changed back to the vB default -> finds the pages

-> but still didnt' display correctly
restored the backed up database again.. .
- downloaded the new language file that you made and are currently using - uploaded it to the default language -> worked i think, i dont' see anything different (but thats me)
changed so it uses the default vB language.
removed the 2nd language in vB.
-> did the upgrade for wiki again -
nice - found it but.. . still not right .. .
-> emptied the catch - little better. still errors -- undefined call and could go no place

-> did the recommendations -- a lot better but still get undefined calls and stops.
parts of it work, parts don't. think its something on his end as has to do with plug ins and ?? .
have a backup before and after wiki if needed .. .
back to the site -- more to do --
****
Can you take a look?
