Hi There,
Thank you for the credentials.
There’s a known conflict between Convertplug and Superfly. This issue has been forwarded to our developers for investigation and found out that the issue is coming from the Convertplug. The plugin developer is now working on this. Unfortunately, we cannot promise an ETA. For the meantime, you may disable superfly when editing in Convertplug. This issue doesn’t affect the frontend. Thank you for understanding.
