Hello After going back and forth with a direct contact at Paypal to setup PayPal Payments on my website. I was instructed to install the PayPal Payments Plugin, and for a day it appeared to be working, although we got 2 cancelled orders, and a failed credit card transaction. The next day because of these suspicious orders, I tried to test the plugin in Sandbox mode. I went to Paypal developers, got my Sandbox merchant ID,, email, Key etc, entered them into the plugin and it crashed upon saving. would entering incorrect sandbox details cause this ? I have since tried deactivating and deleting the plugin, clearing the cache of the site, and reinstalling, but still get the fatal error.
