I recently wanted to switch to this plugin from Events Calendar 3. I temporarily had both installed while I manually copied the event data for each post in my events category, then I disabled the old plugin, leaving just The Events Calendar installed. Unfortunately, it took over my loop -- every category, post, and page became either a listing of all events, or "Nothing found". From looking at the code for these pages, it looks like the plugin's list.php is being called. I tried switching themes, updating my permalinks, and disabling all plugins but this one, to no avail.
Is there a known conflict in switching from one calendar plugin to another? If not, any idea what caused this problem, or how to fix it?
I am running WP 2.9.1 and The Events Calendar 1.5.6.
