Overloaded the cache. There is no mistake now. The page is created normally – both when editing and when adding a new one. JS errors are not observed in the developer console. Thanks.
Updated to version 2.3.1. Made a save in the settings, deactivated and activated the plugin again. The error has been preserved – the error code is the same.
disabling the plugin fixes the problem, but it was set to work 🙂
