2.5 migration problem

Make sure all files are uploaded, try to re-upload the files.

That sounds like some missing or corrupted files. I’d try to upload a fresh copy of the wp-includes folder.

Uploaded files again… no change. ??

Anyone else have a potential solution?

To be honest, I don’t think there is “another” solution. When the ‘undefined function’ error is displayed, it always means a missing or corrupted file, i.e. the file where the function is defined is not there, or has missing lines.

Files can get corrupted during the download, unzipping, upload etc.
Fresh copy means a new download, unzip…

Eventually, you can try a different FTP client, too.

I have deleted the entire site… and downloaded a fresh copy of 2.5… tried two different types of ftp clients… no change. I should have known better than to try the upgrade.

Unless someone can make sense as to why this is a problem, my suggestion to all is to not upgrade. The process is full chock-full of problems and it is anything but simple.
