I keep getting the following Warning when testing my form. I can't seem to figure out where the issue is. Can you help me with this?
When testing I get this-Warning: Cannot modify header information-headers already sent by (output started at/home/hingh3/public_html/webassist/email/templates/Block_HSM.php:39)in /home/hingh3/puplic_html/guest dockage 4.php on line 124.
Is the problem on the form or on the email response? And how do I fix this?
