 * I installed the booking form plugin on this page, it works well but has left 
   behind this script at the top of the page that I don’t know how to remove or 
   rectify?
 * Thanks.

 * Hello.
 * 1) I can not check that page, because its did not published (just in preview 
   mode).
 * You can try this.
 * 2) Probably, its because of conflict with some other plugin or actual theme.
   
   Please try to deactivate one by one all your active plugins at the WordPress 
   > Plugins menu and make testing after each plugin deactivation. If its not help,
   please deactivate all your plugins and active the default WordPress theme. And
   then retest it again. We just need to find the reason of this issue. Kind Regards.

 * Hi, thanks for your quick reply. I’d prefer to not have to go through the plugins
   one by one…

 * I don’t quite understand your last piece of advice, to deactivate all of the 
   plugins and then?
 * Thank You

 * Hello.
    Its seems that you have defined “startmonth” parameter in the Booking
   Calendar shortcode incorrectly. **startmonth** – start month in the calendar 
   after loading of the calendar with booking form. Format of value for this parameter
   is ‘YYYY-MM’. If “startmonth” is skipped the calendar is start showing months
   from current month.
 * For example:
    `[booking type=1 startmonth='2020-05']`
 * Please check more here [https://wpbookingcalendar.com/faq/shortcode-booking-form/](https://wpbookingcalendar.com/faq/shortcode-booking-form/)
   
   Kind Regards.
