 * Hello!
 * I’m sorry to hear that you’re experiencing issues with our Timetable plugin.
 * We haven’t observed any errors on our end, and we haven’t received similar complaints
   from other customers. Could you please try disabling other plugins you have installed
   and switching to one of the default WordPress themes? This will help us determine
   if there’s a conflict causing the issue. Thank you!

 * There are other things going on with this site as well so I’m sure it’s something
   else. Will contact again if we can’t get it figured out. Thank you!
