OK, so you get error stack-traces in a *debug* log, and in the error log you get warning notices? *facepalm*
I have a stack-trace which may be relevant.

That index is very suspicious. Perhaps the page content is so big that it triggers some kind of numeric overflow?
It looks like (to me) this is the problem:
PHP Notice: Undefined index ...
The extension needs to be updated for the version of PHP and Mediawiki you are using.
I would disable it in LocalSettings.php until the author updates it. Or, if you know PHP, you can fix it yourself.
Also see https://stackoverflow.com/a/4261200 and https://www.mediawiki.org/wiki/Extension:Data_Transfer .
