Recently when I am trying to save list as a template in one of the site by going to List Settings -> under Permissions and Management when I click on Save list as template, I got the error as "Sorry this site hasn't been shared with you". You can follow this article
to create list template in sharepoint 2013.
Just to let you know I have full control permission in that site, but still I am getting the error.
The reason is that when you save list as a template, the template (.stp) will be saved in the list template gallery of the top level site not in the child site. So you should have Design permission for the top level site.
If your site administrator does not want to give you full design permission then, they should create a different permission level and assign that to the list template gallary, then you should not get the issue while saving list as template.
