Internal error message
Make sure you're copy of the ConfirmEdit extension (aka the captcha thing) made it over in the move, is appropriate version for your wiki, is set up correctly, etc.
Hi Bawolff,
Thanks for this. However, I'm not entirely sure where to look to find the copy of the ConfirmEdit extension? It doesn't seem to be accessible via the Preferences? Where can you usually check to make sure that it is set up correctly?

You can see if it is installed or not by looking at the page Special:Version on your wiki.
Look in the file LocalSettings.php for a line that looks something like require_once( "$IP/extensions/ConfirmEdit/ConfirmEdit.php" ). Try deleting the line, and see if it makes your error go away (Try this for all the extensions you have installed. However make back ups of LocalSettings.php first).
The actual extension is probably installed in mywikifolder/extensions/ConfirmEdit. You may want to try downloading a new version from extension:ConfirmEdit.
