Your webserver (e.g.: Apache) should be configured to serve static media files from this URL. • Unsafe JavaScript attempt to access frame with URL http://localhost Example: CMS_TEMPLATES = ( ('base.html', gettext('default')), ('2col.html', gettext('2 Column')), ('3col.html', gettext('3 Column')), ('extra.html', gettext('Some extra fancy template')), ) 1.3.
