Plugin working for pages but not for posts

Hi Sayan,

Really liked this plugin and I have already given a 5-Star rating. My client wanted .php trailing extension at the end of the links and this page helped me. Now, I’m seeing that it is just working on the pages and not on the Blog posts. I’m almost on the verge of finishing the project and now while publishing blogs I encountered this issue.

Please help me out as if .php won’t come at the end of the links in blog posts then the client will not accept the website and all of my work would be wasted.

Thanks in advance!
