Hi - I have moved my Prestashop 8.1 site to a new server - from cPanel to CWP.
Whenever I attempt to process a payment the screen eventually returns the error message
Gateway Timeout
The gateway did not receive a timely response from the upstream server or application
This happens on all 3 PSP modules I am running - PayPal, Opayo and Bank Transfer.
On Opayo and PayPal, the payments appear in the PSP's transactions.
I'm surprised this happens on Bank Transfers as this module does not transfer to an external PSP.
Any ideas
