@KoolPal not that I am aware of. I just added it to a site and it worked for me.

@jessepearson Thanks. I realized that one of the plugins I used had changed the email ID slugs.

Now I am seeing some PHP warnings and notices when emails are sent. Can you please guide me? (This is with the debug.log ENABLED)

[11-Jun-2020 11:22:32 UTC] PHP Warning:  strpos() expects parameter 1 to be string, array given in F:\laragon\www\iGMS\wp-includes\pluggable.php on line 240

Thanks a lot!

@KoolPal that could be many, many things. If you're not seeing it once the snippet is disabled/removed, then you may need to reach out to a developer for help. You can also try the troubleshooting here: https://docs.woocommerce.com/document/woocommerce-self-service-guide/#section-4

Thanks @jessepearson I will explore with the plugin author whose email is showing these.

Thanks again
