Welcome to the forums, LowRdrCrzy!
Sorry to hear about your problems installing phpdig. If you can't get install.php to work for you, try creating your database and tables manually, using the instructions located
here . I ended up having to do that myself.
The other thing that might trip you up is making sure that the appropriate permission is in place for those three folders listed in the documentation.
Hope this helps. If you still have problems, post back here. We'll be glad to help.
