I have a problem with blocklayered but it seems recurrent because the same problem appears with the demo template given by prestashop. Category filter doesn't work.

If you install prestashop from 0 and try the demo site, go to women and click on dresses (for example) to filter by category.

The filter doesn't work, it keeps loading but it's never applied.

Console log shows error on blocklayered.js line 495:

Uncaught TypeError: Cannot read property 'meta_description' of null 

Can anyone help me with this issue?? I've been trying all kinds of fixes and posting on forge.prestashop but still no solution...

Thanks.
