got a problem with GS3.0 - cannot save an empty page???

[mvlcek]

i was trying to create a new page when i got this error came up: You cannot save an empty page. i rechecked what i filled in and the website health, everything showed me ok, i refilled the page again, clicked save pages, the error still came up, i still got nothing on my page...

The error message is misleading. It should be "You can't save a page with an empty title.". Did you enter a title?
