Question   Can the file name be changed in the edit page section?

A. The correct path would be:
/adminpages/body-top.html

A. If this section is not editable then it would require changing it from PHP file
If you are familiar with PHP/HTML then you can follow the following instructions
- Go to File Manage
- Click edit page icon
- Search and replace http with https for the button

It's not recommended to do that if you're not familiar with PHP/HTML
If you prefer we can change it for you

A. Yes, with a Pro system this can be acheived by putting the admin in their own membership, and then to modify the html template files for adminpages so that the advanced settings button only appears in the membership that the admin belongs to.

A. No.  You only need that plugin if you want your Members to be able to edit and or modify the pages.

A. These are backups that are made for each person.  So each person has an id and the id is their backup so they can see their most recent backup.  This is only done if using the file manager within the client admin.  If using sFTP or other means to edit the file it does not track changes.
