WordPress MU

If I go to Manage > Pages, then choose a page to edit, if I click any of the toggleboxes/dropdowns there (Custom Fields, Comments & Pings, Page Parent, etc - Publish Status dropdown however works perfectly) they don't dropdown. No matter how many times I click, they stay closed. This also happens when I attempt to write a new page or adjust any of the togglebox options in NextGEN Gallery.

However, if I write a POST, or manage a post, the toggleboxes/dropdowns work!

This was not occurring with MU v1.5.1 - this began with v2.6 and continues with v2.6.1.

- Log out, clear your browser's file and cookie cache, and try again? I'm wondering if some old javascript got in the way there and it's causing a conflict.

- What specific browser and version is this happening with?

This happens with all my browsers, I've even tried other computers and this issue still happens. My browsers include Firefox v3.0.1, IE7, and Google Chrome.

When clicking the button and using Firebug in Firefox, this is what I get:

http://mydomain.com/wp-admin/admin-ajax.php 434ms
http://mydomain.com/wp-admin/admin-ajax.php 429ms

So somehow it gets called twice, even though I just click once. When I do the same thing while in WRITE POST or MANAGE POST, that admin-ajax.php just gets called once. So somehow it's opening and then closing instantly only in Write/Manage Page and NextGEN?

This also shows up in blue on the right side of each of those admin-ajax.php calls:

http://mydomain.com/wp-includes/js/jquery/jquery.js?ver=1.2.6 line 11

Any ideas?

Perhaps you could give us a user account on your installation to see for ourselves.

Just upgraded to WPMU v2.6.2 and the issue remains.

Turn off the gallery plugin and try it again.
CHeck your error logs.

In case someone has this issue in the future, it was a plugin called FeedWordPress that did this. Deactivating the plugin solved the issue.
