Joomla Can't Edit theme - insufficient permissions

can't open template edit receive the following error - anyone know why or how to fix?

Insufficient permissions.
The theme cannot be edited. Please make sure that the user and group running web server is granted the appropriate read, write and execute(linux only) permissions on the following folders. As well as read and write permission on the files in these folders:

/home/ikcroipi/public_html/administrator/templates/isis
/home/ikcroipi/public_html/templates
/home/ikcroipi/public_html/language
/home/ikcroipi/public_html/tmpNEW
Path to Temp Folder is wrong

How to do this for MacOS or Linux systems:

login ssh/terminal under privileged user, get sufficient access rights if need using sudo or su to make next changes
cd {root}
chmod -R u=rwX,g=rX folder_name
For example: chmod -R u=rwX,g=rX app/code/local
chown -R <user>:<group> folder_name
For example: chown -R apache:apache app/code/local
Note: It is general approach. We would recommend that you ask your hosting administrator to grant access permissions for listed folders and files.
