This could be a question for my host or K2, but I am having some difficulty with some of the K2 features. I cannot get the "K2 Tags" to update with any of my new tags (all published, module is set to include everything). Also, the "log in using facebook" option on the pop-up login window does not work, along with the "create article" page for users (It just brings up an error code). Any suggestions?
