Problem creating a new theme

  • I'm using V 1.1.6 of WebCalendar and am attempting to add a theme. I
    simply copied the files for one of the themes in the theme directory and
    renamed them to grace_pref.gif and grace_pref.php. I edited the php file
    to change the value of MENU_THEME element to "grace". The new theme shows
    up on the list of themes when I go to system settings but when I save that
    preference, my menu line disappears. The menu line that displays - "My
    Calendar", Events, Views etc. no longer display. Is there something else
    that I need to do to create a new theme other than just create the .gif and
    .php files in the themes/ directory? Any help would be appreciated.
