Calendar not allowing me to book patients

Situation
I started using OpenEMR last week for my outpatient practice. I have it on the AWS cloud. Everything was going fine, now since Saturday it won’t let me book any patients on the calendar, and every time I try it gives an error:

TypeError: where.jQuery is not a function. (In ‘where.jQuery(mhtml)’, ‘where.jQuery’ is undefined)
URL: http://ec2-52-66-198-166.ap-south-1.compute.amazonaws.com/library/dialog.js?v=51
Line: 530 Column: 32
Error object: “{}”

If anyone could please help me I would be grateful. This is relatively urgent as I can’t book any patients on the calender. I can however register and open a new encounter.
