Thanks for the reply.
I am using free version of Post Grid on my site. As I mentioned before it was working fine before I updated the wordpress to 4.4.1. The version of Post Grid which is presently installed is 2.0.3 and it does not show any update available for installation.
Here is the link to my site: https://bit.ly/1n7YvQi
Please help me solve this issue.
Thanks you again.
