 * I just upgraded my WordPress site manually to 3.2.1 from 3.1 and I got this error
   message at the top of the page:
 * > Warning: call_user_func_array() [function.call-user-func-array]: First argument
   > is expected to be a valid callback, ‘wp_maybe_load_embeds’ was given in /…../
   > wp-includes/plugin.php on line 405
 * Also, when I try to go to /wp-admin/ it gives this error:
 * > Warning: call_user_func_array() [function.call-user-func-array]: First argument
   > is expected to be a valid callback, ‘wp_maybe_load_embeds’ was given in /…/
   > wp-includes/plugin.php on line 405
   > Warning: Cannot modify header information – headers already sent by (output
   > started at /…/wp-includes/plugin.php:405) in /…/wp-includes/pluggable.php on
   > line 934
 * I’ve checked to make sure all the files upgraded. Any reccomendations?

 * Rename your plugins folder to plugins-old and see if you can get in.

 * You could try deleting wp-admin and wp-includes and re-uploading.
