AbuseFilter is probably the most important one, most of the others are just stuff that broke templates, but nothing overly major. If we start getting spam over there, I'll re-enable it, but for now I don't think that is necessary.
I do see the new wiki installation and stuff over here, but I do want to know how you were importing pages, since there is a built-in import/export function that typically works. The other thing is the namespaces: if those aren't set up in the new wiki, then it won't all transfer over properly. There is also the chance that because the versions are different it all is messed up. A lot of the stuff we have is set up for 1.19, although I will look into 1.24 now.
