Ah! An error message!
Okay, then...
Since you are running .760 it is time to the latest version.
Your problem, more than likely, is due to a missed placed/misnamed block in the includes area...
Before you begin back-up everything (files and database).
Do an inventory of your current installed
3rd party modules. This is the perfect time to clean house. Figure out what
3rd party modules you no longer need and uninstall them and delete their directories.
Perform a second backup.
Try to locate all the current versions of the
3rd party modules you want to use. Because with a corrupt core (which I believe, you have) you want to start with a fresh core of
PN, and reinstall the
3rd party modules (to current versions).
If you are good with what I am trying to get at... then go for it.. if you need more detailed instructions (read suggestions). Report back.
