Update 2: If you are still having technical issues, please let me know by email.
Update: It seems the issue was associated with the blog’s theme. I have changed the theme and now the issue is resolved. Sorry if the new theme causes any disorientation. This is probably a temporary inconvenience.
There seems to be a problem with posting comments. This seems to affect only users who are logged in to the WordPress. If you are having this issue, log out of WordPress before you start commenting. You can then post the comment without logging in.
If you wish to post a comment while being logged in, that can be done by logging in after having started writing your comment using the little WordPress icon next to the comment box.
If this doesn’t get resolved soon, I’ll ask WordPress support for help.
