[Zope] Removing the error_log from Zope 2.6

Hi, I would like to turn of the error_log and let all errors log in the stupid log file. Having error messages going to a web page is not really efficient when developing. Also, has anyone a solution for fixing problems with refresh invalidating modular locals when Products are cross linked. (Turning refeash on and off in the Control_Panel/Products isn't really working for me.) (The refresh product that was before refresh got in to the core handle this much better.) Johan
