1) I have a website in oscommerce, and the payment partner is Protx. My old webdesigner put their email address in the VendorEmail field, all I need for someone to do is change it to the address I specify. That's it!
2) The forms on my website do not work correctly. when it is submitted I get the error:
The server encountered an internal error or misconfiguration and was unable to complete your request.
This needs to be recitified. Thanks!
