  • My blog is running at

    As you can see, after the upgrade I have the following error on all of my pages:

    Warning: array_filter(): The second argument, ‘Array’, should be a valid callback in /web/sites/ryanc/ on line 152

    Warning: Invalid argument supplied for foreach() in /web/sites/ryanc/ on line 156

    What do I do????

    Thanks in advance!

  • I’ve got the exact same problem with my blog right after upgrading it. Has some found a solution for this yet or am I just too stupid to get it?

    I’d appreciate all ideas.

    I reverted back to 2.0 by simply uploading copies of the WP files I made before upgrading. Made me nervous doing so… I sure hope somone has some answers so that I can get back up to 2.01.

    I have ZERO plugins on my installation and a custom theme.

    Well at least it’s not me. I have no idea how to get the backup files that I saved…how do you upload them?

    I’ve just tried to upgrade my WordPress 2.0 installation and got the same error. I had just renamed my wordpress directory to wordpress-old, so it was very easy to roll back to the previous version. Hismuse, where did you save the backup files? How did you get the new update onto your server?

    I have a similar error.

    If this is a known error and is expected to be fixed, it is very important for getting my installation back up and running.

    This is a large and popular site (20,000 hits per week).

    I am having some issues with my database backup file, so I need to try to resolve through upgrade.

    Similar error to what? What’s the error message you receive?

    What version of WordPress did you upgrade to?
