The Call to undefined function add_action() does not make sense. That is a core WP function. If CSV Import is being loaded, it has to exist. It can only be loaded if WP is loaded.

My best guess is something else with in the WP install has hijacked the action=import query very, very, early is the WP loading process without checking which page is doing the calling.

I’m going to have to suggest doing the plugin conflict test. It also possible that the theme is the source of the issue.

In regards to the license key, what is the key? I’ll look it up. what site are you trying to activate it on? Reply back as a private reply.
