User Follow and up vote down vote feature not working

Hi Rahul,

Thanks for this great plugin. I installed this plugin in my website http://www.dogmal.com/dog-questions But there are some issues I facing.

1. When User follows other user in my site, It shoes the success message but in real it’s not working. It’s not showing any followers or following in user profile.

2. When user up vote and down vote any question, it showing the null value. and not working.

can you please suggest the possible solution of it.

Thanks
