Sometimes readers’ comments don’t appear in our blog post articles. My friend had this problem. There are more than 100 comments in her blog, but none gets displayed in any post. So what must be the problem:
Profiles & comments
If you’re currently using your blog from Google Plus profile, you shouldn’t activate . This will not only hide all your comments from your blog posts but also removes comments link from drop-down menu.
Readers comments setting
When you write a post, on the right side of post article body space, there is one button named Options. Click on it and on Readers Comments, you should choose Allow.
If you have been using third party templates earlier and now have shifted to free blogger template, comment codes used in former may not be compatible. Or you have done some changes in HTML which aren’t compatible. Therefore, you have to revert all the changes and also revert widget templates to default.
Login to your blog>Click on Template>Click on Edit HTML>Click on Revert Changes>Click on Revert widget templates to Default>Click on Save Template.
Once all above steps are incorporated, check your blog once more. If those comments, which didn’t appear visible earlier are now visible, you must have got it right. Cheers!
