I just upgraded from Pligg 1.0.1 to Pligg 1.0.3b and I was having problems logging out. Everytime I logout I get a blank page. Yankidank, founder of Pligg posted new login.php which is supposed to solve the problem. I saved the file for future reference so here it is! Please take note that it goes in the /libs/ directory and not the root (/) directory! You’ll mess up your Pligg install if you do that!
