On a site where I have Pligg installed, there is a category called "All" in the header. When clicked, the page that loads is blank. I deleted this All category from the database and everything was working fine. However, when I woke up, the site had an error "There is a problem with the categories table. Error CA:001." So I tried adding the All category back but that didn't help. I had to remove everything and start over, but now I'm back to having the All category and if you click it, the page is blank. Any help?
