Title: Two small errors with WP2.0 Last modified: August 18, 2016 --- # Two small errors with WP2.0 * Resolved [edwinkort](https://wordpress.org/support/users/edwinkort/) * (@edwinkort) * [20 years, 4 months ago](https://wordpress.org/support/topic/two-small-errors-with-wp20/) * After the upgrade to 2.0 I get the following error * Warning: array_filter(): The second argument, ‘Array’, should be a valid callback in /home/bookiebo/public_html/blog/wp-includes/capabilities.php on line 152 * Warning: Invalid argument supplied for foreach() in /home/bookiebo/public_html/ blog/wp-includes/capabilities.php on line 156 * It doesn’t stop me from working with WP, so it’s not really important.

I deactivated all plugins prior to upgrading. * Thread Starter [edwinkort](https://wordpress.org/support/users/edwinkort/) * (@edwinkort) * [20 years, 4 months ago](https://wordpress.org/support/topic/two-small-errors-with-wp20/#post-304172) * Nope, I was already half way the deleting of the scripts, when I noticed that i had to deactivate the plugins. At that time, I couldn’t go back of course. * Any idea on fixing this? * [kjarrett](https://wordpress.org/support/users/kjarrett/) * (@kjarrett) * [20 years, 4 months ago](https://wordpress.org/support/topic/two-small-errors-with-wp20/#post-304173) * Did you make a backup? If so, FTP the files back to the server. If you didn’t make a backup … :/ * -kj- * Thread Starter [edwinkort](https://wordpress.org/support/users/edwinkort/) * (@edwinkort) * [20 years, 4 months ago](https://wordpress.org/support/topic/two-small-errors-with-wp20/#post-304179) * It looks like the ‘Ultimate Tag Warrior’ plugin was broken. I de-actived it, and iall seems okay now. * Thanks to all. * [kahleeb](https://wordpress.org/support/users/kahleeb/) * (@kahleeb) * [20 years, 4 months ago](https://wordpress.org/support/topic/two-small-errors-with-wp20/#post-304203) * It looks like the CG-Amazon tag is what is not fully compatible with WP 2.0 for me. Once I stopped using that plugin, the problem went away. It is a shame since I really like that plugin too. * [vkaryl](https://wordpress.org/support/users/vkaryl/) * (@vkaryl) * [20 years, 4 months ago](https://wordpress.org/support/topic/two-small-errors-with-wp20/#post-304204) * There’s a couple of other amazon-type plugins around. Try a search, there’s one called “AMM”…. maybe one of the others would work better. * Also, you might hit [http://chait.net/](http://chait.net/) and contact David Chait about the incompatibility. * [ina_kulot](https://wordpress.org/support/users/ina_kulot/) * (@ina_kulot) * [20 years, 4 months ago](https://wordpress.org/support/topic/two-small-errors-with-wp20/#post-304251) * I am using the AMM plugin already, but am also getting the same error as the ones above, and also these: * Warning: Cannot modify header information – headers already sent by (output started at /home/angelaso/public_html/inarage/wp-includes/capabilities.php:152) in /home/ angelaso/public_html/inarage/wp-includes/pluggable-functions.php on line 221 * Warning: Cannot modify header information – headers already sent by (output started at /home/angelaso/public_html/inarage/wp-includes/capabilities.php:152) in /home/ angelaso/public_html/inarage/wp-includes/pluggable-functions.php on line 222 * Warning: Cannot modify header information – headers already sent by (output started at /home/angelaso/public_html/inarage/wp-includes/capabilities.php:152) in /home/ angelaso/public_html/inarage/wp-includes/pluggable-functions.php on line 194 * The external blog ([http://derpinsel.com/inarage](http://derpinsel.com/inarage)) looks fine, but I can’t log in and I can’t disable the plugins from where I am. Am on shared server. * [waraxe](https://wordpress.org/support/users/waraxe/) * (@waraxe) * [20 years, 4 months ago](https://wordpress.org/support/topic/two-small-errors-with-wp20/#post-304341) * Has there been a fix for this yet? * V, can I comment out anything in capabilities.php to relieve this? I really have the CG-Amazon plugin integrated into my site… I’d like to do whatever I can. * Interesting that the errors only happen in IE, and not FireFox or Opera. * [jade2001ad](https://wordpress.org/support/users/jade2001ad/) * (@jade2001ad) * [20 years, 3 months ago](https://wordpress.org/support/topic/two-small-errors-with-wp20/#post-304381) * Hi, i’m having this problem too, but in my case it IS stoping me from working with WP becuase it’s disabling my navigation bar at the top with the options for the plugins, posts etc. Even when i type the extention in the browser itself all it get is a page with the two error lines, and my blog page has the error lines at the top of the page too. * Th thing is i can’t even seem to access the plugin page to disable the offending plugin :-S * I’ve already tried deleting the AMM table from inside phpMyAdmin hoping that would help and refreshed but i still have the error. * What do i do? I don’t want to have to reinstall my whole database again from a backup…arg!
