Hi @jarldev,
Thank you for creating a ticket!
A plugin is fully compatible with default WordPress user roles.
We have not tested our plugin with a custom user role. The current plugin version is not supported the custom user role. Currently, we do not have any method to add extra custom roles into our plugin.
In the upcoming new version1.1.0 ?of our plugin, we are not using this cf_add_unfiltered_html_capability_to_users function anymore and in version 1.1.0 ?we are allowing only WordPress default user roles. Still, we are not having any method to support custom roles. Maybe in the next versions, we can think about that.
If you still have any questions. Please let me know.
Thanks!
