Occasionally, when trying to save a post, the result is, instead, an immediate logout and back to the login screen. Occasionally, attempting to login does the same. I am using Firefox; the 'cure' is to dump all domain cookies, a feature in a Firefox extension. This is fairly irritating, of course. The solution would likely be to upgrade, but the hosting service I'm using (iPower.com) is running a version of MySQL that is incompatible with the newer version.
I can use it in this fashion but it's a nuisance. Any ideas?
