RSS Feed showing blank and not validating for Feedburner (Blogger to WordPress)

I recently migrated from Blogger to WordPress. I did 301 Redirect of all posts pages etc from thenewipadblog.blogspot.in to thenewipadblog.net which is running in wordpress.

However my feed for thenewipadblog.net/feed shows blank
When i try to validate Feedbuner it is giving me an error telling its not a valid XML Path. I don’t understand. Have I done something wrong here or is it a theme problem cause the comments feed at https://www.thenewipadblog.net/comments/feed is working and shows the xml code and everything. So why is my main feed causing problem.

I am also using another plugin that redirects posts /%year/%monthnum#/%postname%.html to /%postname.html

Here is my .htaccess file so that you can understand whats going on:
