 * Hi
 * I sometimes have the problem, that the calender is not working, when I change
   to the next month. It then says “Permissions check failed!”. I am using caching
   plugins. In the Autooptimize settings I excluded “wp-content/plugins/advanced-
   booking-calendar” for javascript and css optimisations. As for W3 Total Cache
   I added all links under minify >> “Never minify the following JS files” and “
   Never minify the following css files”. Any other idea?
 * Best regards
    Christine

   to see the link]_
