Impossible to check config : infinite load

Hello,

Since the last update, I can’t check my configuration before a restart. If I’ve an error, it’s show me a red message with the error line. However if everything is ok : nothing, just an infinite scroll (instead of the classic ok message in green).

Do you have an idea ?

When I check console log of my browser, I can see this :

Error 405 : api/config/core/check_config - Method Not Allowed

Thanks.

Update : anyone ? :confused:
