Hi, first time poster in need of some advise :-)
I have a SharePoint 2013 Enterprise environment set up (one application server + another database server). One site collection with a few subsites.
* Top-level site
** Subsite #1
** Subsite #2
** Subsite #3
All subsites have their own unique permissions (SharePoint groups). I am administrating the site collection as a Site Collection Administrator. I'm able to create my own custom permission levels on all subsites as needed. I need to create a new custom permission level only available on this one specific subsite*.
*This is the one subsite where I cannot create my own custom permission level. I can confirm via the site settings that neither permissions nor permission levels are set to inherit anything. As far as I can tell this subsite isn't configured any differently than the other subsites.
1. Go to the Top-level site and create a custom permission level which will be made available on the subsite. I would like to avoid this approach as it would no doubt lead to much "clutter".
2. Delete the entire subsite and create a new one, move all content here. I would also like to avoid this approach as I need to learn why it happened so I can avoid it in the future.
Can someone please help me understand why this is and how I can solve the problem? Feel free to ask me anything as I suspect I have overlooked something somewhere.
