I have a webserver with multiple domain and user accounts setup. Recently I renamed one of the domain names and changed it's username correspondingly. However, this new user cannot access the data from the domain because it does not have the required permissions.

How can I solve this problem? I've tried chown and I still cannot get access to the files. I have SSH root access and this is the only way I can actually move/touch the files but the webserver displays the file through another username which does not have access to the files.

Thanks
