Hi, on one of our client's website we are now getting the following error.
Error reported: Callback to: https://acceptance.acumenbusinesslaw.co.uk/plugins/ClientAcceptance/wpcallback.aspx: failed CAUSED BY invalid HTTP status line: >null<
Server Reference: ukdc2-pz-pay11:callbackFailureEmail-33196:MerchReq-823-4
Nothing has changed on the system for a long time.
We got this error a few days ago:
Error reported: Callback to http://acceptance.acumenbusinesslaw.co.uk/plugins/ClientAcceptance/wpcallback.aspx: NOT OK, received HTTP status: 301
Server Reference: ukdc1-pz-pay06:callbackFailureEmail-1042:MerchReq-588-57
So we updated the callback path to include the https (instead of http) in case this was the problem, but we are now getting the current error.
Please can you help.
Thanks in advance
