Encountering an error when trying to send mail
Have been using UE4 and am just now getting the following error message on the trigger page for sending my newsletter:
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/davcow9/InnerchoicePublishing.com/mondayEmail_trigger.php on line 63
I've attached a screen shot of the code referred to. Don't know how to resolve this issue. Please help.
