Looks like you have variables in your LocalSettings.php is encoded wrong.

Look for $wgSitename line in LocalSettings.php Change it to be exactly: $wgSitename = "WikiZ\xC3\xA9lia";

This should fix your problem with the wrong encoding in the title (The \xC3\xA9 is a fancy was of writing &eacute;). (I'm unclear how you're seeing an &amp;eacute; - I get a unicode replacement character)
