   hello everybody!

   I have a problem with my WP after upgrading 2.3.3 WP to 2.5 or 2.5.1 (the same database and problems):

   Warning: array_keys() [function.array-keys]: The first argument should be an array in /wp-includes/widgets.php on line 1337
   
   Warning: Invalid argument supplied for foreach() in /wp-includes/widgets.php on line 1337
   
   Warning: Cannot modify header information - headers already sent by (output started at /wp-includes/widgets.php:1337) in /wp-includes/pluggable.php on line 694

   Does anyone have any suggestions how can I resolve my problems? :)

   I would check your RSS widget in admin->design->widgets to make sure the settings are right or there period. You could also try turning this widget off to see if it helps.

   You're right, maybe this is it <->

   Fatal error: Cannot use string offset as an array in /wp-includes/widgets.php on line 1023

   but this widget was turned off...

   Is it totally removed from the side bar?

   before You've asked it was turned off (this RSS 1 widget)

   any sidebar, widget and plugin is working now.

   A possible fix might be http://wordpress.org/support/topic/169107?replies=6

   "Stick this in your theme's functions.php file:
   delete_option('widget_text');"

   "After you can see the blog and login again, remove the above line"

   You might give it a shot as it looks alot like the problems you are having.

   No need to throw the baby out with the bathwater. Just do another UPGRADE but this time, delete the unwanted files from your server first. THEN upload the fresh files. That way there's no chance of file corruption. (Well, there's LESS chance of it.)

   So:

   delete these folders on your server:
   /wp-admin
   /wp-includes

   delete all the *.php files from your WP root, EXCEPT
   wp-config.php

   Also DO NOT DELETE:
   .htaccess
   robots.txt

   Rename your /plugins folder so WP can't find the plugins .. you can rename it back after the upgrade.

   Point your browser to the upgrade script (located at /wp-admin/upgrade.php) and all should be fine.

   It doesn't work :]

   Maybe I should manualy change some "autoload" values from "yes" to "no" in my database in the table "wp_options"? What do You think about this solution?

    I've been trying to upgrade to the latest WordPress 2.5.1.

    I've tried the Automatic upgrade that didn't work.

    So now I'm tying the manually upgrade. But I got stuck on this part:-

    "The wp-content folder requires special handling, as do the plugins and themes folders. You must copy over the contents of these folders, not the entire folder. Copying the entire folder overwrites all your customizations and added content. Also take care to preserve the content of the wp-config.php file in the root directory."

    Anyone out there who can give me a more detail explanation about this? Thanks.

    Hello, sorry for my bad english. Same error in my blog after upgrade to 2.5.1. I resolve the problem with these steps :

    - connect admin
    - go to theme->widgets
    - remove all widgets of side bar
    - save

    The error disapears.
    The new value of "wp_options->widget_rss" is now : a:0:{}

    Hope helps you...

    I tried all these steps but can not even log into my admin.
    Re-installed the whole thing again and still no luck.
    This is what I get:
    

    Warning: array_keys() [function.array-keys]: The first argument should be an array in \wp-includes\widgets.php on line 1337
    
    Warning: Invalid argument supplied for foreach() in \wp-includes\widgets.php on line 1337
    
    Warning: Cannot modify header information - headers already sent by (output started at \wp-includes\widgets.php:1337) in \wp-includes\pluggable.php on line 690

    Help?
