Hey Christina,
Thanks for providing the login details. I checked your Superfly setup and it’s not limited to display on certain pages only so it looks like all of your settings are correct.
I believe that you are already familiar with the basic troubleshooting procedures. I’ve read the whole thread and I didn’t see details if you have tested for a plugin conflict and if the issue is coming from your child theme.
I’m afraid to switch to the parent theme in your site and deactivate plugins as it is a live site and it doing so will interrupt your live site’s operation. With that said, please first switch to the parent theme and check if the issue persists. If it’s fixed, a custom code in your child theme is likely causing the issue, in which case, you should consult with a developer to fix the customization.
If the issue persists after switching to the parent theme, it’s likely a third-party plugin is causing an issue. Please deactivate all plugins except Cornerstone and Superfly and reactivate them one by one while checking if the issue persists each time. Just in case you need some guidance on performing a plugin conflict test, you can watch the tutorial below.
If the issue persists after switching to the parent theme and deactivating plugins, it would be best to copy your site to a staging server so we could perform the basic troubleshooting steps again to double-check and we can do deeper troubleshooting after that without the risk of breaking your live site. If you can’t do the staging site, please allow us to do the troubleshooting steps that I’ve mentioned once again and perform deeper troubleshooting after. Just note that it will disrupt the operation of your live site.
Thanks.
