I'm currently developing a site which uses Authors and the author.php template for listing all articles written by that author. For some reason the author.php template is not being used on one specific author (Url is: /author/kristian-poulsen ) instead the e-commerce template page-cart.php is being used. If I rename page-cart.php it uses page.php, so for some reason the system thinks it's a page. It works as it should on all other authors.
I've discovered the culprit is the WP e-commerce plugin (Version: 188.8.131.52) , disabling the plugin makes the author.php template being used on the "Kristian Poulsen" author. I've tried different things like regenerating Permalinks and switching theme back and forth.
Someone has an idea to what would be wrong?
