Based on the header information this is all I have; Request: GET Referrer User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729) Fatal error: Call to undefined function wfMemoryLimit() in /usr/home/wiki/public_html/w/includes/Setup.php on line 165 getting this error in our email reports. Going to the URL however does not produce the same fatal that the email reports show.
That sounds like you've got some old files mixed with new files. Looking at trunk, I can't see any reason this would happen.
I'd agree with that diagnosis; closing out as a worksforme. A common cause of this kind of problem is having the old MediaWiki files still in another directory, but referenced explicitly from the LocalSettings.php in your new directory.
