Hi, I already change the php file host, the message "could not verify serial number" is gone. But when I fill in details, when I click next, nothing happens..
Together I attach the DB details, hope it helps, thanks
Nevermind, i just realised i cant use free hosting to store my db. But i already host my db & validatation file in GCP. Now I get the same error, the serial number is invalid, although I already key in the SN in DB.
