X3Photo Gallery Forums

I installed imagevue version 1 and everything worked fine. I then tried to install version 2 and that's when everything went wrong.
I followed the instructions for updating to version 2 but I keep getting error messages after I tried to open the links. (error log shows files don't exist)

But to make things worse, both of the two forums (Simple Machine Forums) I have running on my site cannot be accessed anymore!
I get "500 Internal Server Error"

How could me installing imagevue in a separate directory effect my two forums?

Any ideas or suggestions would greatly be appreciated!

It's okay, everything works now.
Apparently I changed some CHMOD permissions to 777 when I should have left them at 755.

Thanks!
