The site setup goes like this. Top site ---> Subsite1--->Subsite1.1
Subsite1 is inheriting permissions from top site. Unique permissions are set for Subsite1.1 and due to that users on Subsite1.1 have "None" permissions on Subsite1 and Top site.
Now the problem is that the users of subsite 1.1 are not able to access this site. Whenever they try to access subsite 1.1, they get access denied error. I checked and it seems no unique permissions are set for Site Pages library or home.aspx. Whenever they are added to top site permissions , then only they are able to access subsite 1.1 which is not I want.
SharePoint 2013 is being used. Kindly help.
