Hi @loncar,
I noticed that if Polylang is activated, the easy appointment plugin is not creating IDs if I add new location, service or worker. It creates entries with empty ID field, so when I refresh the page or move to another page and return back, they disappeared.
If I deactivate Polylang, the plugin works fine. Also, reactivate Polylang has no effect on current entries, just that I cannot add new ones.
BTW, it is a great plugin, thank you for that.
