Hi there, A local shop asked me to take a look at their OSC site a few weeks ago as the payment module for Paypal Pro kept throwing back the following error - "Error Payment module configuration error. Please verify the login credentials." I've been all round the houses and looked on the forum here but to no avail. Nothing seems to work. I have checked with Paypal and the details entered into the module are 100% correct so it must be a section of code somewhere. Anyway if anyone can help it would be much appreciated :( Cheers, Peter
