I recommend to remove this line:
Disallow: /modules/
Because when modules permalinks are off, then all module content begins with http://your.site.com/modules/index.php?r=/abc/de/, as the result most of your site content will not be indexed.
So, please remove this line or make a notice regarding modules permalinks setting.
