Re: Bug report: Extension DataTransfer

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?
