Displaying "Array" everywhere and cannot post

[lorenzone92]

The issue seems to be caused by some PHP cache software like Zend Optimizer. In many box is displayed the word "Array" and the administrator can publish nothing; when you click on the "publich" button WP will post it as a draft.

The user Seveneth found a fix:

in /wp-includes/plugin.php [Line : 102], inside remove_filter function.

Change:
unset($GLOBALSwp_filter?[$tag][$priority][serialize($function_to_remove)]);

To:
$wp_filter[$tag][$priority][serialize($function_to_remove)] = array();
unset( $wp_filter[$tag][$priority][serialize($function_to_remove)] );

The remove_filter no longer uses serialize(). Might want to see if the new changes fixed the problem.

Thank you for getting this in trac!

ryan responded on wp-hackers: It should already be fixed. What version is being used? Beta 1 should have the fix.

lorenzo replied: I downloaded the beta and I've seen that the fix applied is a bit different
from the one purposed by seveneth...
I'll try if it works asap...

Closing as fixed for now.
