sohail virk on "My Website Isn't Working After Updating Wordpress"

Hello! I really need help. My website isn't working after updating from 4.4.2 to 4.5. What should i do ? here's a link http://www.winblow.ml and the screenshoot here . Thanks for help

which plugins are installed?
which theme is installed?

This is the last thing displayed in your page source code:

<!--noptimize--><!-- Autoptimize found a problem with the HTML in your Theme, tag </body> missing --><!--/noptimize--><script type='text/javascript' src='http://stats.wp.com/e-201615.js' async defer></script>
<script type='text/javascript'> _stq = window._stq || []; _stq.push([ 'view', {v:'ext',j:'1:3.9.6',blog:'95157713',post:'85',tz:'8',srv:'www.winblow.ml'} ]); _stq.push([ 'clickTrackerInit', '95157713', '85' ]);
</script>

- For plugins, last thing i remember is Jetpack, WP Super Cache, Accesspress Anonymous Post, Social Login, wp Discuz Comment, Buddypress, kk Star Rating, WP-Optimize and that's all.
- Theme i used now is Accesspress Magz

So, what should i do next? i can't login to wp-admin and else. Thanks for help and reply.
