The best way to solve this would be to turn off all modifications by selecting all of your products and turning them off in Plugins & Products -> Manage Products. If you are unable to disable your products, put this

PHP Code:

define('DISABLE_HOOKS', true); 


before the ?> in your config. Then turn all your products off and remove the

PHP Code:

define('DISABLE_HOOKS', true); 


in your config.

Then turn all of them back on one by one and find out which one is causing the problem.
