When posting please look at it when you are done, I can edit and reformat but I did that for the last one.
As on the other request, cannot assist you without knowing what you are using, your plugin environment for one. Please see forum guidelines
Your site has this error:
Uncaught TypeError: $ is not a function
at (index):11

Use any dev tools and inspect and you can see, Has someone has copied over or migrated site incorrectly. This is the r=error that is thrown.
