I am trying to use Contact Form 7 with WP ProfitBuilder. The code loads OK when I try to use it and submit the form, it shows rotating arrows and never completes the action. Contact Form 7 support indicates that this is a compatibility issue with the theme ( I am using WP ProfitBuilder) or another plugin…
I tested this on my site and had no issue. See the video to show you what I did… I would check with your host to see if they are blocking anything and get them to check their message.log.
