If the Woopra software is giving you problems, then exit and relaunch the program and it should work fine. As with all betas, there are still some glitches with the new release, and we're working to get those fixed and a new update released.
Also, the blog post announcing the updated release mentioned downtime with servers as Woopra is updated across servers around the world. The improvements in the server code are incredible, but it takes a little time. Be patient. It will be worth it. Woopra is running faster than ever now with improvements from beta testers and the developers.
I am NOT using the plugin and have used Woopra successfully for nearly 2 or more months. I opened up my console this morning and the only site I really track was missing, and the API key now says "null".
I also checked my other sites, and all are connected with the javascript in the pages (no plugin) and none are recording visits. :(
The desktop woopra app run well but no way to have the analytics in wordpress dashboard. With the last plugin version for WP the design is better but it didn't run before and didn't run after plugin update.
