Error after 3.1.3 automatic update? Querry error.

Hi everyone,

after having updated to 3.1.3 I’m experiencing the following error:

“Warning: explode() expects parameter 2 to be string, array given in [path] wordpress/wp-includes/query.php on line 2390 [and 2399]”

This error pops up when I select “Media -> Library” from the admin menu.
I haven’t experienced it anywhere else.

Everything was fine before the update.

Note: I used to have Jetpack installed, but have first deactivated and then removed it via the Admin panel because googling for the error often brought up that particular Jetpack plugin.

No change.
Error persists.

Plugins I’m using:

Akismet
Antispam Bee
Contact Form 7
WordPress Database Backup
WP-Optimize

That’s it.

The error doesn’t do anything but burp up those lines (very irritating) and, as far as I can tell, everything seems to work otherwise.

Any ideas?

Thanks for reading.
🙂
