How to Fix error: Cannot comment Facebook ,Comment Failed to Post post on facebook comment web. On lots of websites (news, blogs, buzzfeed, etc) you are able to post comments by logging in through facebook. I log in, my profile pic shows up (says my name on the side and everything), I type in my comment but when I submit the comment it says "You are not logged in. Please login and try again.". I have tried on multiple computers, logging in and out of facebook, different browsers, adjusting my privacy settings...I don't know what the issue is. Help please?


Method one


The problem most likely is that you have cookies and site data disabled. In Chrome I fixed this problem by going to: Settings-->Show Advanced Settings (at the bottom)-->Content Settings
Uncheck: Block third-party cookies and site data

Method 2:

My personal Facebook ID seem to have gotten blacklisted after I posted comments which were "too Christian" on a couple of liberal websites. However, I can still post comments using my small business ID.

At the bottom of the Social Plugin comment form, it says:

Posting as {my name} (Change)

If I click "(Change)" then it lets me select between my name (my personal Facebook ID). Posting comments on news articles works fine if I use my business name. Posting them with my personal Facebook ID does not work.

My guess is that someone who disagreed with one of my Christian comments -- perhaps a moderator on a liberal web site -- falsely reported me to Facebook as violating some policy, and Facebook then blacklisted me on ALL sites.
