Community polls was previously working fine on my site. I just renewed my membership and installed version 4.2.1. CJLIb is 2.2.6. I should point out that there was no update message via the joomla updater for the update. What I did was simply install polls again manually. Even now, I see that 4.2.2 is available but the polls CP says up-to-date -- maybe that's normal.

On the front-end some things changed after the update -- the poll results and voting became unavailable and were previously available. When I changed some settings on the backend I was able to get rid of the message saying that poll results aren't available but now the vote now and view results buttons don't actually function.

Also, I've enabled the share features, but I don't see any share options on the polls.

Here's a link to one of the polls... http://actionfigureking.com/toy-and-comic-book-related-breaking-news/417-action-figures-toys-and-collectibles-podcasts/the-walking-dead-season-5-is-lori-still-alive
