delinea You can share the error screenshot i sent with the URL t them. This is not something to fix in the template. its problem from hosting side that not allow you to save anything 403 is a forbidden error. Try to downgrade the PHP version. I saw you have another site JA Focus but on different server and no issue in that.

Kindly check now, i am able to save settings : http://prntscr.com/xc6ko4
I used Admin tools extension on your site for fix permission, may this solve the problem.
