I have installed the Plugin Advanced Custom Fields and the ACF Multi Dates Field https://wordpress.org/plugins/acf-multi-dates-picker/ so I can be able to pick different dates on posts but after having selected the dates, I realize that they are not reflected in the WP Fullcalendar calendar. I am not very good with the part of the code so I need someone to help me to know what part of the php code I should modify from the WP Fullcalendar plugin so that the dates are reflected.
