Shopping Cart Randomly Stopped Working

[Mi Kull VAHS]

Hi All,

I have been doing this for a  couple of months now and haven't been in the Cpanel file directory in some time, only accessing administrative functions from the actual PrestaShop application. I can't figure out why but whenever someone tries to add something to their cart (including me) this error pops up. Any advice would be greatly appreciated.

 

Impossible to add the product to the cart.
textStatus: 'parsererror'
errorThrown: 'SyntaxError: Unexpected token < in JSON at position 0'
