On custom post type we can only edit snippet

Hello,

Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.

It seems like a plugin conflict. I tried to check but the troubleshooting mode of the Health Check plugin is not working on your site. You can check yourself by deactivating the plugins one by one.

If you want us to check this further, please create a staging site and share the login details with us. Here is how to create a staging site: https://www.wpbeginner.com/wp-tutorials/how-to-create-staging-environment-for-a-wordpress-site/

Looking forward to helping you.
