Hi,I\'ve followed the steps specified in the documentation for changing "newave_portfolio" to a custom slug, but it won\'t change.

Make sure you refresh the permalinks by pressing 'Save' in Settings -> Permalinks

Check to see if the .htaccess file is writable in Settings -> Permalinks (usually you get an error message if it isn't)

If the .htaccess is not writable, even though you specified a new permalinks structure. the webserver will still follow the old rules defined in the .htaccess file
