Luc one more thing if you have not seen it yet which will break things is a vbulletin setting for the base url. If you set in vbulletin to always use the forum url as the url then it can break images etc across any program in
vb that has relative image urls. I have been saying for years all programs need to have full urls always defined for things and not use relative but you know just something to consider when you look at peoples sites and see a mess up check that setting and make sure it is set to no.
