Today I upgraded my personal franchise blog from WordPress 2.1 to WordPress 2.6.2. I know, what a big upgrade… To do so, I simply went to my webhost admin panel and used their one-click upgrade service. Within 2 minutes I received an email from my host telling me that everything went fine.
So I tried to go back to my blog admin panel but it would not let me in. Every time I entered my login and password, it would just go back to the login page. I tried typing wrong password and it would give me an errror message. Going back to the homepage of the blog, I realized it was showing me as logged in. Strange.
That’s when I decided to use my secret troubleshooting weapon…. Google (I know, it’s no secret weapon). I googled “can’t login to wordpress after upgrade” and I the first result thta popped up was a page on WordPress forum.
This is the solution I used:
I had this problem after I updated my WP. Tried everything… cleaning out the cash, the cookies, changing the admin password, making changes in the wp-login.php, making changes to wp-config.php.
The last thing I tried was to clean out all of my plugins, deleting them from my ftp (after downloading everything to my computer!) and then when I tried to login I got a message that my database neded uppdating because it didn’t “fit” to my wordpress installation. An now… I can login!
But this also seems like a good fix:
I’m having this problem when upgrading to 2.6.2 with Fantastico. Here’s the process that’s been consistently working for me to correct it:
- Using FTP, rename the
pluginsfolder (at/wp-content/plugins/) toplugins-old- Log in as usual
- I am prompted to upgrade the database, so I click that button and it does
- Rename
plugins-oldback toplugins- Log in again
Once I do that, everything seems to work.
If you’re having any login issue after updating WordPress, you may want to try any of the fixes.

Hi Ricardo,
Thanks for your comment but I figured it out and added the fix to this post.

Just to say – ive renamed my plugins folder and went through the database upgrade and then renamed the folder back to plugins – and it all worked fine. Annoying and disconcerting problem.
@Nick – yes, that’s what I should have done. I’ll know for next time…
I just don’t update when a new version comes out, too much hassle.
Best Post Ever!!!!!
Thank you!
Thank you, you´re a lifesaver!
Hey, same thing here, same upgrade as well. Thanks for the fix. Bless you and bless Google for finding you.
Tried all this and still cannot login to my admin panel. I don’t know what to do. Nothing works. Can’t get in. What a nightmare. I have thousands of people who use my site, and I am sitting here with my finger in my nose without no solutions. I hate this. Any ideas where I can turn next?
Thanks a lot! I was suffering this for a long time and I can’t identify the problem.
Thank you.
