I recently updated one of my sites to 2.9.2 and everything seemed to be going fine. Then last friday a user called me to say she couldn't login. When I tried to login myself this morning, I couldn't login either.
Here's the errors I get:
ERROR: Incorrect password. Lost your password?
ERROR: Cookies are blocked or not supported by your browser. You must enable cookies to use WordPress.
I was fairly certain it was the right password. And I have cookies enabled on all my browsers.
I went into the database and reset my password. I get the same errors.
I also searched the forums and didn't find a resolution that worked. I tried deleting and reinstalling my wp-login file as instructed here: http://codex.wordpress.org/Login_Trouble
Could it be a plugin issue? I used the site with new version for several days without any problem. I do have two login plugins installed (login lockdown and chapsecure) as I had a problem with two of my other sites getting hacked when I was on 2.8.4. I have not tested deactivating all the plugins yet (it always freaks me out a bit when I do that. :))
When I tried to reset my password via the forgot link password option, I got the initial email, but when I click on the link it brings up a blank page.
I'd really appreciate any thoughts and help with this. Let me know if you need any additional info.
Thanks so much!!
