Seems the plugin interfere with something in my WP. As soon as I enable a popup on my page, it stops any other feature from working and it doesn’t work either. As soon as I disable it, the page now works fine. I am using Visual Composer and Jupiter theme from Themeforest.
Sorry to hear that you are unable tot get Popup Fire working. So when you activate Popup Fire through your WordPress admin panel there seems to be a problem will all other parts of your site?
Do you have a test site that you can use to test Popup Fire without your theme or visual composer? If you do have a test site please go ahead and deactivate all your plugins and use a default wordpress theme, and then see if Popup Fire works. This will tell us if the problem is a conflict between visual composer or your theme.
Please let us know if you have any other questions.
This is actually a problem with the latest update to version 2.1.4. We have since fixed this issue and just submitted version 2.1.5 to Code Canyon. Once they approve this update you will receive an email and then you can update Popup Fire directly from the WordPress admin panel :)
