Blank pages after restore

because something went wrong with a module, i maked a backup of my folders and the database. After that, I imported the backup.sql nad i moved the language folder and the template back to the new installation. everything works well, except for the productpages.

When i click on a category, i can see the products with their description. But when i click on a product, i get a blank page.

I already reset the auto increment teller in my database and removed all my products. I tried to make a new product, but i get the same blank page.

I tried the debug utility but i can't open the logs (permission denied, not the owner)

Try uploading the files to your server again. I copied a site last week and got similar errors and found that I was missing a few key files.

If you are using the classic / default_template try uploading the includes folder from the ditribution zip file.
