Problems with saving messages

There are sporadic problems with saving messages when new messages is not saved after several attempts. Problems appear today. I work with Mantis translation. I use monobook.

I have noticed the same thing, already before I enabled LiquidThreads. I type something in the edit screen, and just before saving, it will revert to the old contents. Can you confirm this is the observed behaviour?

Sorry, can't clarify more. I didn't notice blanking of message text during saving.

I confirm.

I also have had problems saving new messages, but only when I cut and paste from the screen above, usually when there is a link which is not translated. Nothing is saved. I didn't notice blanking of message text during saving either. I use Mozilla Firefox and the default skin.

Then it is probably gone now that I have disabled some UsabilityInitiative extensions. More details below. Raymond promised to look into it and report whatever he finds wrong. Confirmation appreciated.
