Pages List Frequently Out of Sync with Menu

I’ve been using this plugin for years (probably 5) on multiple sites (probably about 80). I like that this give WordPress a much-needed intuitive interface and drag-and-drop functionality, but on many of my sites (if not all), it eventually breaks, and does not sync with the menu. This is a common complaint with my clients, too, that the changes they make aren’t reflected on the site.

WHY?! I’ve used every setting, tried this with multiple themes (even my own), used it alongside other plugins, and no plugins at all, and it’s always given me the same problems. It sometimes works, sometimes doesn’t.

How do we fix this? Does anyone else have this problem? Does anyone else notice that making changes in the Pages list of Nested Pages sometimes doesn’t reflect in the menu? Or sometimes creates pages that aren’t there? Or makes duplicate pages as links? Or puts them in the wrong place? Even if I remove the page in Nested Pages, it doesn’t necessarily reflect in the menu.

Yes, sync is on. I’ve also tried manual sync, turning sync on and off, etc. It’s frustrating that such a necessary plugin doesn’t work. That means my sites don’t work.

Thanks,
Brendan
