Do you mean it was a total blank page? This could indicate some other issue (Blank page is usually a PHP fatal error if error reporting is disabled. It'd be a good idea to enable error reporting just to rule out this case).

Generally if the $wgScriptPath related variables are wrong, you're more likely to get 404 pages and urls constructed incorrectly, the worse case that could possibly happen is a redirect loop.

https://domainname.com/wiki/mediawiki/index.php/Special:UserLogin generally looks like a correct url. It could be something about your set up interferes with path info stuff. You can try just setting $wgUsePathInfo to false at the bottom of your LocalSettings.php (This changes the url from https://domainname.com/wiki/mediawiki/index.php/Special:UserLogin to https://domainname.com/wiki/mediawiki/index.php?title=Special:UserLogin which works better on some webservers.
