I’m glad to see you managed to roll back successfully. I would’ve missed you :-)

What happened to your blog? I upgraded today and everything went finer than froghair.

@Robert - it was all in the admin area. I couldn’t get to wp-admin. EVERYTHING I did to fix that didn’t work. : (

So, um, not 100% sure. I rolled back until I can figure it out.

I have heard of a couple others with major issues. I think I will hold off a bit.

Same thing happened to me a week ago. After a minor panic, we ended up reverting to the previous version of WordPress, which I like better, anyway.

I had problems with it as well. I got a 500 internal server error and was unaware of this for nearly 4 hrs.

Chris,

backup, backup, backup!!! :)

Heh, I know a good unix admin that can keep your blog in tip top shape for you :)

That really sucks. I wonder what went wrong?
Are you on LAMP?

I know people diss Dreamhost, but in all honesty, I just updated TWELVE(12) WordPress sites to 2.6 in under one hour using the one-click update. 10 different themes, all glitch-free.

In all honesty, I would NEVER-EVER roll-back to a previous install and think that solution is solid.

My 2.1.1 install was hacked. And worse, Google removed me from all indexes. I blame only myself for not updating.

Here’s the story: http://www.redesign.creativecomponent.com/is-there-life-after-google/

The important part of this story is that you were able to recover. To quote Jeff above, “backup, backup, backup!!! :)” With backups any problems can be corrected. Somehow.

One step lots of people forget is to disable all plugins before the upgrade. No idea if that’s what happened to you but I figured it’s worth emphasizing!

Do you run any admin side plugins? I cannot think of anything that would be that major between 2.5.X and 2.6. I know there were plenty of enhancements but not sure what would have been done to cause breakage.

Anyway, I am glad your blog is back up. Hopefully you will be able to make the transition soon without issue.

I am also faced this problem in 2.5.2 last week, and it happened after changing my password from my control panel. I thought my site is hacked.. After changing my password in the database and waited for a day without accessing my wp-login.php page. It came automatically after 1 day.. I don’t know how it came :)

I was backed up. Really.

And no, I don’t have very many plugins at all. Only 8, and one’s for comments, one’s for SEO, one’s for FriendFeed.. you know, all content-side.

I just (nervously) upgraded and it all went well. It stinks that you didn’t have the same experience… 2.6 is a nice update!

Now I’m wary. Should I be? Should I wait?

Interestingly, I also had this issue. I couldn’t log into the admin panel no matter what account I tried.

Luckily, simply deleting the browser cookie for my sight in Firefox took care of the issue and I was able to log right in. Everything’s working fine after that.

I have read around the internet that there was a redirection issue involved in the /wp-admin index that was causing people some issue. Perhaps this is what @Rick Mahn had experienced. Maybe what went wrong with yours.

[…] have been some folks having issues with the upgrade. Chris Brogran, famed Twitterer and blogger, reported that his upgrade didn’t take and he had to roll back his installation. Sounds like the Wordpress team needs to spend a little […]

Darn - if I only read this yesterday. I borked my blog too. Hooray….
