I have the same issue as of yesterday in version 2.2.1 and I’ve been looking all over the forums here for a fix.
As of last night, when I hit save, save & keep editing, or publish, I am taking to post.php, but despite the URL being post.php, I’m at the main page of my blog. The auto save seems to be locking up / not working. I have a post right now that’s been sitting for 10 minutes and the autosave is stuck on “Saving Draft…” Another new post hasn’t autosaved at all, but I get the above error when I attempt to save or publish it.
I attempted to edit the time on my autosave file, my version doesn’t have that bit of code. This worked perfectly until last night – no new plugins, files, etc. I simply blogged, and then tried to blog again 20 minutes later and found that I couldn’t any longer.
Anyone?
