I am having some trouble with the categories on my installation. I have 1474 categories and 17077 images that take up 5.9 GB of space. I'm not sure around what category things stopped working but I can no longer view the Edit Categories page in the admin area. It just comes up with an IE error message as if the page is totally missing. I also have a sitemap mod installed and this stopped working too. I use a custom script to add categories since I add so many at one time. This script includes a part that autosorts alphabetically. Is it possible that I have done something wrong with the cat_order field? It worked just fine until about a day ago when I added about 100 new categories. I am using version 1.7.1. I know that 1.7.2 is out now but I have made so many modifications to 1.7.1 that it would be hard to basically start over from scratch. Any ideas about what might be causing this issue would be greatly appreciated.
