Prestashop Layered Navigation Block is no longer working

[amar.prestashop]

Hi,

 

From a couple of month our Layered Navigation Block is no longer working.

Our Prestashop is Base on v1.5.6.2

 

I do not the reason why but it stopped working, i've checked the version and updated with the last one available for PS v1.5 ( v2.2.0 ) but nothing change

 

A sample link: https://www.casanova1948.com/en/wallets-6#/gender-men-unisex

If i add a filter or remove one nothing change

 

Could you help me or suggest me an alternative module for PS v1.5.6.2 the Upgrading to PS v.1.6.x is too complex ( so many customizations ).

 

Regards,

Amar

There is a js issue in the blocklayered.js

 

Please check the console for more information.

 

function cancelFilter() has the problem.

 

Thanks,
