Admin Edit Category/Sub Category Problem

[SoulieBaby]

Hey everyone, I'm currently running 4images 1.7.6 and there seems to be a problem in the Admin section - Edit Categories. You can click on the little + box to open a category, however when you try to open a sub category it just goes back to the main category screen. See the URL for an example

Open Category - http://www.souliejolie.com/gallery/admin/categories.php?action=modifycats&s=3cc34d9b896622449e4e5aa5d0ddcf1d&opencat=2 <- this expands the category into sub categories.

Open Sub Category - http://www.souliejolie.com/gallery/admin/categories.php?action=modifycats&s=43d743e38265c9a622744f7c57c36ac2&opencat=18 <- this used to expand the sub categories, however it closes all the categories again (goes back to the main edit category screen with all of the categories closed)

Could someone please help me out! I'm not sure if anyone else is having this problem, but I hope it's an easy fix!!

Thanks

Leanne

Try clicking the smaller + and - signs above saying edit category, opens all allowing view and edit of all cats.
