Why Comments Are Not Showing on Facebook

Settle this before you change a single setting, because the two cases share nothing.

A comment hidden by a Page filter or by a moderator drops out of the public thread but stays visible to the person who wrote it and to their friends. Facebook sends no notice to either side. The practical effect: the author of a hidden comment will swear it is right there on the post, and they are looking straight at it while they say so.

The second case never leaves your own session, and one test separates the two. Open the same public post logged out, in a private browser window. Comments there that your feed refuses to show mean nothing on the Page is filtering anything, and the fault is yours to chase. Identical views mean the post itself is filtered, and the fix belongs to its owner. The same split decides what to do when your own comment disappears from someone else's post.

On your side it is usually a stale app. A thread that spins forever, loads three comments and stops, or sits on Unable to load comments is half-loaded rather than moderated. Force close the app from the recent-apps switcher rather than backgrounding it, then pull the post up again. Still stuck? Clear the app cache in your phone settings, then load the post in a mobile browser. The browser is your control. Full thread there and a gap in the app means nobody moderated anything.

Facebook does not hand you a raw thread. Near the comments on most posts sits a sort control, usually reading Most Relevant (on desktop, at the bottom right of the post), and tapping it offers Newest and All Comments. Meta documents the control on Page posts and on your own profile's posts, so a stranger's profile post may offer none. Most Relevant favours people you are connected to and comments that collected replies or reactions, so a perfectly real comment from a stranger with nobody answering it can sit below the fold indefinitely.

All Comments is the setting people are actually looking for. Facebook's own description of it says it includes potential spam, the clearest admission you will get that the default view is a filtered one. Switch to it on a busy post and replies you had never seen come up.

Two more things swallow comments inside the thread itself. Replies are nested behind a View replies link, so a conversation twenty comments deep shows as one line. And the count printed under the post generally includes those replies, so hand-counting will almost always leave you short of it. The ranking side deserves attention of its own, since the reactions a post collects feed straight back into which comments surface first.

If the post belongs to a Page, check moderation first. Pages can keep a list of blocked words, and a comment containing one is hidden automatically and silently. Meta does not document how closely the list matches, and admins report short entries catching longer words that contain them. If your Page still offers a separate profanity filter, it works the same silent way. Nobody gets told. The comment never appears publicly while staying visible to its author.

Meta moves these controls between Page settings and Business Suite, so look in both. Word lists are usually the work of a previous admin, or of your own panicked afternoon two years ago. Read the list out loud before deleting anything. That is the fastest way to spot the entry eating half your thread. A longer walkthrough of what to change when a Page starts hiding comments covers the rest of the moderation surface if the list turns out clean.

Separate from anything you set, Facebook runs its own classifier over comments. The rules are not published. Meta does document how to approve a comment on your own post marked as spam, reached from the notification or the post's menu. Page admins have more to work with, since hidden and flagged comments generally appear in the Page inbox or the moderation area of Business Suite, and can be unhidden there. The symptom is the same either way, a comment that exists for its author and shows up for everyone else only under All Comments.

The patterns that draw it are ordinary. Comments carrying links, especially shortened ones. Long runs of identical text under one post, which is what a giveaway or a tag-a-friend campaign produces. None of that is documented as a rule, and treating it as a rulebook would be a mistake. There is no setting to switch off here, because you never switched one on. What you can change is how the comments read, and keeping comments from reading as spam is mostly link discipline and variety.

If there is no place to type, the thread is not hidden, it is closed. For public posts, Facebook offers a control for who can comment: public, friends, or only profiles and Pages mentioned in the post. Set narrowly, everyone outside that audience loses the comment button and sees the count with no input field. Page posts can have commenting turned off outright, and posts restricted by age or country behave the same way for people outside the audience.

The default lives in Settings under Followers and public content, and it can be changed post by post, which is why one post accepts comments and the next one does not. Open the post menu and look for the comment control there. Turning commenting back on restores the thread as it stood, and the input field returns for whoever the audience setting allows.

Some disappearances are real. A block removes two people from each other's view, so a thread can lose several comments at once and look censored when it is only two accounts unable to see one another. A deactivated account hides its profile, and Meta does not spell out what becomes of comments it left elsewhere; some drop out of threads, others stay under a name that no longer leads anywhere. Reactivating restores what went missing. A deleted account takes its comments permanently.

Then the ordinary possibility: the commenter deleted it, or the post owner did. Neither leaves a trace for anyone else. And a thread can be empty because nobody wrote in it, which every check above confirms and none of them fixes. Threads are easier to join than to start. That is the thinking behind services that seed a post with its first few comments, so the next reader arrives to a conversation rather than a blank box.

Write down which check broke the case, because the cause repeats: a Page with one bad word on its list keeps eating comments every week until someone opens that list and reads it.

Tap the sort control above the comment thread, usually labelled Most Relevant, and choose All Comments. Facebook's description of that option notes it includes potential spam, so it shows material the default view withholds. Then expand each View replies link, since nested replies stay collapsed regardless of sort order and count toward the total printed under the post.

Usually an account disappeared and took its comments with it. Deactivation hides the profile, and Meta does not document what happens to comments left elsewhere; some vanish from threads until the account is reactivated, others stay under a name that no longer opens. Deletion removes them for good. A block between two people hides their comments from each other in both directions. Beyond that, the commenter or the post owner may have deleted the comment, and Facebook leaves no visible trace of either action.

Commenting is closed on that specific post. Facebook lets the author choose who can comment when publishing, and if the choice was friends only or mentioned profiles only, everyone outside that group sees the comment count with no input field. Pages can also disable comments on individual posts, and posts restricted by age or country behave identically for people outside the audience.
