Remove Strip category don’t work

Hi, we have activated the “delete category function” (stripe category base) on our woocommerce shop, but it doesn’t work and create some problems.

We have exported our website to hosting with a test platform.
I leave you the accesses to check what the problem is.

Moreover, within in the shop on the subcategory pages, if we want to load more products in the list, the system does not load them.
Look at this url for example:
http://www.stllonch-prueba.com.mialias.net/categoria-producto/recambios/recambios-cafeteras/

at the bottom of the page, to click on “ver mas productos”, it doesn’t work!

I wait for a feedback.

Many Thanks. Cheers.

Alessandro

p.s. The error that appears above the header does not affect (it is an error only appears on the test platform, while on our server it does not appear).
