This is a continuation form my last post 'Themes'.
When editing the config.php or styles.php through the file my server's cpanel' file manager the link to the styles.php seems to get broken. That is, changes made to the config.php file can be seen when moodle is run, eg. the colours are changed but control of the fonts through styels.php is lost and all fonts in the edited theme revert to browser default. Furthermore when logging in after an edit I get the brief error page '...headers already sent' before being logged on.
??????????
Thanks in advance
