I am running a newly installed D6.6. Suddenly, and suddenly I can't edit any nodes. I am running as admin (user 1). When I click edit, I see the edit screen, but when I click save, the edit screen is merely redisplayed.
I've tried disabling YUI wysiwyg editor, to no avail. I tried different browsers, to no avail. I tried logging out and back in, and I tried emptying the sessions table. I installed devel module, but still wasn't able to discern the cause of the problem.
Any advice about what might be happening?
Thanks,
Bo
