Hi @jkahansky Welcome to Mass Planner and our community! We're glad to have you here.
Regarding your issue,
You are trying to publish posts from your blog to Facebook by using RSS Feed, right?
Check these options:
Keywords: if you added some keywords to this field, Mass Planner will extract only posts that do contain those keywords,
Excluded keywords - maybe you added some keywords here so Mass Planner won't extract posts containing those keywords. and
Ignore feed items without images - If you have this checked and some items (posts) in your rss feed do not have images, Mass Planner will ignore them.
Make sure you check these settings. If you still have issues, contact support.
