What's going wrong
Owners of WP Twitter Auto Publish report that automatic tweets stop going out and the logs show API errors. Some see 401 unauthorized or invalid token messages, others 403 errors saying the app lacks permissions or has only a subset of endpoints, and some see 429 too many requests even when the site sends only a tweet every half hour. Several believe the cause is X changing its free API tiers and access rules, and they are unsure whether to upgrade, change settings, or wait. Site owners who depend on auto publishing for traffic need a clear diagnosis and a warning before access changes break their posting.
