Does it seem like you’re losing all changes when saving a recipe? We’ve found that this can happen in combination with some caching plugins/solutions.
Specifically we’ve seen it with LiteSpeed Cache if the “Cache REST API” setting is enabled on their Cache settings page. Try disabling that.
We’ve also seen it with Cloudflare Caching. Try disabling that to test if it works then. If so, you could add a Page Rule to skip caching, similar to skipping the Cloudflare Firewall.
Your caching plugin/solution not listed here? Caching is still the most likely suspect. Try deactivating caching for a second and see if the problem occurs then as well.
