Hi @sviluppomania,
I made a new WordPress install. I installed the latest version of qTranslate from GitHub and the latest version of Burst from the repository.
I activated the “Slugs translation” integration, and unfortunately, I can’t reproduce the issue. Do you have more settings turned on that influence the WordPress rest routes?
Can you check in the console what the rest routes are with the setting turned on and with the setting turned off?
You can check by doing the following in Chrome(Other browsers should be similar):
1. Inspect the page
2. Open the network tab
3. There is an input box named filter, type in ‘fields/get’
4. Click on the request, and you should see a Request URL.
5. Can you send us the request URL with the settings turned on and off? You can strip your domain if you like.
Kind regards,
Hessel
