1. Thanks for the post Ryan. I ran into the same problem tonight and wouldn’t have thought about just deactivating the plugins. Three seconds later and I could upgrade again.

    Hello Ryan,

    good idea to post this! I have found that a lot of wordpress users have trouble with this. I had this exact same issue too, and your solution worked until 3.1.1.

    But now, trying to update to 3.2.1, it does not work. I deactivate 14 plugins, and try the automatic update, and it fails, giving me the error again. Havent found a workaround yet. If you do, would be interested to know.

    trying to update to 3.2.1.

    It worked fine for me. I used the BULK ACTION and turned off all the plugins and the update from 3.1 to 3.2.1 worked flawlessly

    Ryan! A Merry Christmas to you!
    I was running a WordPress development version and could not update to 3.3 due to that fatal error in class-http on line 1426.

    Tried various “fixes” including php.ini turn off safe_mode and various memory configs.

    Then I found your suggestion. I had turned off a number of plugins but NOT ALL.

    Deactivated rest and got my Auto Upgrade lickety-split!

    Thanks for the tip!

    Cheers and Happy New Year!
