http to https now calendar has disappeared

I just updated from http to https
see https://cartagenacolombiarentals.com/property-searches/ working fine but when going to individual pages even though the link is there as before ie [dopbsp id=14] it is not showing there https://cartagenacolombiarentals.com/rental/casa-victoria/

SAYS IN ELEMENTS SECTION CHECKER:

Uncaught TypeError: jQuery(…).DOPBSPCalendar is not a function(anonymous function) @ (index):901j @ jquery.js:2k.fireWith @ jquery.js:2m.extend.ready @ jquery.js:2J @ jquery.js:2

Thanks
Martha
