I'm using JSN Epic FREE edition and everything was going on well until I found out that the folder 'JSN_Epic_FREE' doesn't give me permission to change anything in it, including the favicon and logo. I checked my FTP permissions for all the other folders in my server and it's working fine. This problem occurs only for this folder.
I tried using JoomlaXplorer but the problem remains the same. Any suggestions as to how to solve this please?
