Not able to Post Comments : Comments not working in blogger with custom template

I have experienced the problem with comments when I have switched to custom template from blogger's standard template. If you are using blogger's custom template and no body is able to post comments on you blog then please check bellow settings for the comments first:

1. For the blog which you are not able to see the comments, from Dashboard go to Settings -> Comments here you check following comments settings are proper
2. Comments --- Show is selected
3. Who Can Comment? --- Here select Anyone or Registered Users as
4. Comment Form Placement --- Full page
5. Comments Default for Posts --- New Post Have Comments

Please make sure above settings are done then save the comments settings and check whether are you able to post the comments or not?

If still you are not able to post the comments then please perform following steps:

1. For the blog which you are not able to see the comments, from Dashboard go to Layout -> Edit HTML
2. Select check box Expand Widget Templates
3. Now from the HTML template search for word "Post a Comment"
4. This word should be between <a expr:href='data:post.addCommentUrl' target='_blank'> and </a> (i.e. it should be like <a expr:href='data:post.addCommentUrl' target='_blank'> Post A Comment </a> ) if Post A Comment words are between some other HTML tags then change it to as given in sample
5. Click on Save Template button

Now you are able to post the comments on your blog.
