Issue: You may encounter 404 errors after adding FancyPost blocks, meaning the page or post doesn't load correctly.

Solution: This issue often occurs when permalink settings are misconfigured. Go to Settings > Permalinks in your WordPress dashboard, and without making any changes, click “Save Changes.” This will refresh your permalink structure. Also, ensure that any slugs or URLs generated by your blocks are not conflicting with existing pages. If the problem persists, check for plugin conflicts or issues with your theme’s permalink settings.
