need help dont understand unix commands in bold. Getting "
An error occurred" right after license acceptance. Guessing its a file permissions thing.
You need to be at a shell prompt to run those commands. Also, please check with your host for the proper permissions to use for php files and directories within your site. 666 is always a bad idea and is a leftover from when most people used an FTP account to update their stores where now, most sites use http.
It will probably be easiest for you to simply have your host set the appropriate ownerships and permissions for you if you are not experienced at the Unix/Linux command line.
You could also use a FTP client like FileZilla that lets you bulk change permissions on files, folders or both.
