Sorry, but we don’t guarantee that our themes, free or premium, will work 100% if used in a WordPress multi-user environment.
Why not? Simply because there’s too great a variation in paths, subdomains and subfolders etc. and it just doesn’t seem to be possible to cover all eventualities – at present, anyway. This isn’t particularly the fault of the WordPress multi-user developers – it’s more about how Apache, mod_rewrite and the whims of hosting sysadmins fit together at the moment.
Themes can be made to work – on an individual basis, depending on your installation. But a lot of this will involve editing of paths in the theme functions.php, both for wp-content/ with things like loaded jQuery scripts and also wp-includes/ for including basic scripts, such as jQuery itself, permalinks and even images.
Also, not everyone has access to their server’s http.conf – and there are a number of tricks here, mainly involving AllowOverride, that can be used to get results with multi-user. It’s no good saying do this, and our themes will definitely work, if you can’t get at the actual file…
You might get lucky, if there’s luck in programming, and it will work straight out of the box – but, as I say, no guarantee.
