Well, first of all, I would always recommend that you install MediaWiki manually, because in many cases MediaWiki installation is messed up by auto-installers.

See Special:Version on the wiki to determine if your webhost inadvertently installed anything related to authentication (such as wordpress).

Also see Manual:LocalSettings.php to make sure that $wgServer is set to the correct place.
