All of the sudden I've started receiving this error in my datafeed:
Non-static method rc4crypt::decrypt() should not be called on line 205 / And again on line 278.
I'm using the Parsing code from David Hollander: https://wiki.foxycart.com/v/1.1/transaction_xml_datafeed
I'm running a simple mysqli query that inserts / update the order, but even after removing the custom code it will give still give that error.
Any idea on how to fix it?
