"There has been an error processing your request" on product page

[kaiserberg]

Hey,

I have already checked the other posts regarding this error message and came this far:

After installing magento and activating the Shopper Theme I can't access my product pages anymore. The error message I get looks like this but I can't find out a solution for what magento is telling me:

Go look in your var/report/ folder for a file named with the number displayed, post the contents. As asked, "There has been an error processing your request" is so generic and the area it occurs so unspecific that it's anybody's guess as to what's going wrong.

Also, since this is an installed theme, you probably would get far quicker response about some issue they've already encountered if you ask them for help.
