Your plugin(s) should have some sort of mail test, which you’re probably using, but should provide some debugging.
If they’re using PHP mail(), which is probably the default configuration, that’s not a great option. Sending straight from the server with PHP usually has issues, as it’s really not a great mail handler. That’s why I use the SMTP Plugin. Though I use it with mailgun’s free plan and it works amazingly well.
Well, that’s a good start. I don’t think I use either of those form plugins any more, so I can’t help troubleshoot why they’re not working. Since the SMTP plugin is working properly, maybe the Plugin forums at Wordpress have some ideas.
Your cPanel DNS is no longer used, so that shouldn’t be an issue.
Unfortunately caldera forms is stuck at creating forms, whenever I click on create a form nothing happens. Do you know a workaround or another plugin that worked for you too that may avoid my related issues?
Also, if someone have any tips on how to resolve this in cloudflare I’d appreciate it.
It’s certainly a problem with cloudflare or its integration with smtp mail plugin or forms because I wasn’t getting this issues before I changed my DNS to cloudflare servers.
I just changed wp mail smtp settings to php (I’ve used other smtp and sendgrid before) and now the forms are working.
I don’t know if that helps to understand the problem better, but I would like to still try to change since some say it’s not recommended to set php on wp mail smtp plugin.
