Photo 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!

Not sure if that's even possible to affect any other separate folder on your server. What's the link to your gallery?

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

Thanks!
