Sorry, but I'm Spanish and translation to your post not quite understand it, (I do the dialogue through translators)
In my shop, the templates are in html/template/html/com_virtuemart/category, formerly in the 2.0.4 version if it was them and could select them in the administration of VM. In the following versions have disappeared in the Administration and not teach them, although there are.
I have to say that also named them differently, so I have the original in order to make comparisons in updates, my templates named them as sugo_categories.php for example.
now, although put them in wiev of VM folders not it shows them me.
I understand that something happened in the code for that previously worked perfectly.
Thanks in advance for your selfless help.
