I have a company website for an online marketing advertising agency. When viewing the website with Adblock Plus activated, it disables all the website's CSS stylesheets, although the website has no ads at all.

The website is constructed using Wordpress as a CMS and a custom template, but the problem appears with the default Wordpress template too (twenty twelve, twenty three...)
(Sorry for posting this twice, I forgot to mention the website's URL at first)
Adblock Plus blocks CSS on my website
Looks like this is caused by the Spanish filter list called Filtros Nauscopicos. You can report that to the author here: http://nauscopio.wordpress.com/category/filtrado/
