I have the same problem with blank screen in frontend after installing Template with Gantry Framework but it says following:
Warning: require_once(/domains1/do2655600/public/www_rootgantry-fusion/formatter.php): failed to open stream: No such file or directory in /domains1/do2655600/public/www_root/modules/mod_roknavmenu/helper.php on line 129 Fatal error: require_once(): Failed opening required '/domains1/do2655600/public/www_rootgantry-fusion/formatter.php' (include_path='.') in /domains1/do2655600/public/www_root/modules/mod_roknavmenu/helper.php on line 129
i have split your post from the original topic as it seems to be a different issue and the other one was already in the solved board, so nobody else besides me would have looked at it.
if you like send me your link and super admin details via pm to take a closer look.
I'm getting the same error after I tried to make another template default ..
