how to allow unregistred users to view normal posts [closed]

It is a strange and rare bug.

While publishing our last post we checked the “Blog” and some other
categories in the category section.

In our previous posts we never checked the “Blog” category.

Initially, when I tried to reproduce the bug, I didn’t noticed it.

We again tried to reproduce the bug and this time we have identified the bug.

I am not sure whether the bug is in wordpress or our site development team.

I wonder how checking a category affects the behavior of “Strangers”!

If any one know where the bug actually lies, please let me know.

We have corrected the problem in our site and the above link is now working fine.
