WordPress custom taxonomy pagination not working

Hello,

Working in a portfolio site, we need to publish a list of projects from a category, but this category is a custom taxonomy. As there are a lot, we need to paginate results.

Problem is explained here: https://stackoverflow.com/questions/5792709/wordpress-custom-taxonomy-pagination-not-working

I have tried to find a solution in this forum also with no success.

The problem is when reaching page 3, it returns: no posts found.

Hope somebody can provide us with a solution. Thank you.
