Thread:Project:Support desk/Error 404 - Object not found. Internet access to wiki/reply

404 means file not found. If it was a permission problem you'd probably get a 403 forbidden.

Appears to be a re-write rule problem. Your $wgArticlePath is set in such a way to redirect to a directory that doesn't exist (for example, without redirection http://wiki.hal1.se/index.php?title=Main_Page&action=view works) It also thinks the style directory is somewhere other then it is, so there is probably a mismatch between what is in LocalSettings.php (for $wgArticlePath type variables) and what you have in your apache config.
