Hi guys,
I upgraded from 1.6 to 1.7 and now i have a big problem.
I even tried to upgrade now to 1.8 but i have the same problem.

Now when i try to open any product on my website i get the same problem (i attach the picture) and now i dont know what to do.
I get this same error when triying to upgrade to 1.8
