General Support: Undefined Index error and Manage issue

Just installed plogger, and have a couple of issues. No idea if they are related as unfortunately I'm not fluent in php at all!

First, whenever I'm logged into the admin section, I have this error message across the top of the screen:
Notice: Undefined index: JPG Support in /home/stopanti/public_html/gallery/plog-admin/plog-admin-functions.php on line 1986

I did initially also have assorted Depreciated Function errors, but I solved these by following the instructions here. ie: Download phpThumb_5.3_fix.zip: http://sourceforge.net/tracker/?func=detail&aid=2991128&group_id=106407&atid=643974
And extract the files to "plogger\plog-includes\lib\phpthumb" overwriting everything (you may want to make a backup before hand just in case).

The other problem I'm having is that I'm unable to manage albums or individual images. If I click on the Manage tab, it takes me (correctly) to the Manage Content page, where I see a list of collections. But if I click on a collection, or the "edit" button, instead of it taking me to the correct link (eg: http://stopantivaxnetwork.com/gallery/plog-admin/?level=albums&id=2), there is a pause, and I'm redirected to the upload page. So there's no way for me to add, edit or delete albums.

My host is running Apache 2.2.15 and MySQL 5.0.92-community and PHP 5.3.2, if that info helps.


Many thanks for any assistance.
