 * I created my site on a dev environment and the plugin worked well.
    I migrated
   this site with all in one migration to another host and since as soon as I activate
   the plugin my site is down with fatal error:
 * “Uncaught ValueError: Unknow format specifier “R” in … /restaurant-reservation11/
   includes/Settings.class.php on line 1276″
 * How can I resolve this?

 * Hi kainette,
 * That line is part of what generates the Time Format option (in the Basic area
   of the Settings page). Perhaps you are using an invalid character in the time
   format you are trying to specify. Try leaving that setting blank. Does it work
   then?
