Need some help debugging a website

Hi,
I'm looking for an expert WordPress developer who can help me to identify and correct bugs in a client's website. The site seems to be suffering from a lot of jquery related issues.

The site is at https://workingspacelondon.com/

The main problem is that the property details pages are not displaying any property details - see https://workingspacelondon.com/offices/serviced-office-north-row-mayfair-w1k/

I'm currently trying to get a back up restored but will still need some help to identify the causes of this problem that only starting happening yesterday.

Thanks
