Hey there I just wanted you to know that after this last WP update there seems to be some sort of conflict between the Royal Theme and Contact Form 7. After doing updates today to ALL plugins and WP the contact form would no longer work. I tried deactivating all plugins except CF7 but it would still not send (continuous spinning).
I then activated the 2017 WP theme and it worked just fine. I then re-activated the Royal Child and it again would not work. I restored the site to before the updates and the the CF7 forms are working again.
I just wanted to let you know. I will wait for a Royal Theme update before doing the updates again.
We do not face this problem on our test site. Could you please provide us with temporary wp-admin and FTP access in the Private Content area? Can we update the theme on your site to be able to check the problem? Please confirm that you have a full backup of your site, theme options, and DB.
