Thanks a lot Caleb,
when I changed to Woocomerce 2.6.4:
> The filters wrong: after select a option in a box the web doesn't response.
> The style is not aplicated correctly: for example if you access to the url https://tienda.ulpgc.es/producto-ulpgc/ropa/ the style in combo box COLOR you can see a little box yellow, blue, etc.... So after update to 2.4.6 I can't see any style in all combo box.
After read your answer I agree with you that the issue is relationed with my theme, so I must revice my code theme.
The webs where I use Woocomerce filters are:
https://tienda.ulpgc.es/producto-ulpgc/ropa/
https://bolsaviviendas.imp.ulpgc.es/
So in the next weeks I must revice my theme and sincronice correctly with Woccomerce.
Thanks a lot.
