After installing the XenForo 1.4.5 upgrade, none of the VaultWiki style sheets (templates) are being called into the wiki pages. This results in no styling being applied to any elements on the wiki pages. We have temporarily fixed the problem by manually copy-and-pasting the contents of ALL VaultWiki .css files into the main Xenforo header.css style sheet. Are there 1) any bug fixes within the new version that would have caused this and 2) will we have to do this every time we upgrade in the future?
We checked with the VaultWiki developer and they didn't have this particular issue when they upgraded to 1.4.5 earlier this week. Thanks in advance for any assistance you can provide.
Really, we couldn't comment on this because we don't know how that add-on works, nor do we know what other customisations you have in place. As far as I can recall, there would be nothing that should cause that.
In my experience it's extremely rare for any XF release to break anything unless it's a major second point release. So, no.
