Hi @agave1
After reviewing the Mailer Lite plugin in more detail, it turns out that it’s not really a bug or conflict between Mailer Lite and Popups for Divi, but rather a limitation of our free plugin:
Mailer Lite creates the signup form dynamically (via JavaScript) after the page loaded.
Such dynamic elements are not supported by Popups for Divi, but require Divi Areas Pro: After installing the premium plugin, all Popups will instantly support dynamic content without any further changes.
Since upgrading to Divi Areas Pro is not possible due to your budget, you can review your Mailer Lite form and see if there is a way to insert a “static form” (maybe there’s an option for that, you could also reach out to their support).
A more “Divi-ish” solution would be to remove the Mailer Lite form and instead use a Divi “Opt-In Module”. You can link your Opt-In module to the Mailer Lite account → https://www.elegantthemes.com/integrations/mailer-lite/
Please keep me updated on how this goes. Also, let us know if there’s anything else that you need help with.
p.s. as this is no bug, but a known limitation of our free plugin, I’m going to mark this thread as resolved for now. In case you feel the issue needs to be reviewed again, don’t hesitate to re-open this conversation
