A channel won't take this post
The post wasn't built for that channel, or the channel doesn't accept this kind of post.
What you see
Publishing to one channel is refused, or the channel is greyed out in the composer.
- This post wasn't built for: tiktok. Reprocess it for those channels first.
- Instagram doesn't support text-only posts — add a photo or video to publish to Instagram.
- Audio-only posts aren't supported on this platform yet.
Why it happens
Each channel gets its own version when you process a post, so a channel you didn't tick has nothing to send. Some platforms also need media: YouTube, TikTok and Instagram have no text-only post, and Pinterest needs an image or video.
How to fix it
- If the post wasn't built for the channel, reprocess it with that channel ticked, then publish.
- If the channel needs media, add a photo or video, or publish the text to a channel that accepts text.
- Check "What will post" in the publish dialog to see exactly what each channel receives.
