Day #43 in the Big Wiki house

Installing an RSS reader extension has broken user login.

Only on the commercial paid-for hosting mind, not my own crappy in-house box, which works.

This is A Known Bug (FFS!) See, "There seems to be a problem with your login session; this action has been canceled as a precaution against session hijacking."

If tempfile space starts to fail for some reason, MediaWiki login fails. It gets its cookies in a knot (Why?!), and fails with the exquisitely incomprehensible error message above. This may be triggered by writing temp files (such as, for instance, caching RSS feeds.

This is why PHP coders shouldn't be allowed nice things.

Why am I using RSS?
- Because I want an embedded Twitter feed.

Which in turn requires the conversion of a sensible URI
To a magic chicken-sacrificed URL like this

Finding that magic number requires the use of illicit 3rd party websites and voodoo. For commercial reasons best known to themselves, Twitter offer the feed in RSS format, but won't tell you what it's called.

Then you just have a world of pain with MediaWiki being rubbish about cached files breaking logins to deal with.

But disk space is an operations issue!
