Rest v10 issue OAuth2 after upgrading to 7.9.1

Hi André, 
all the files permissions are correct. Main platform works well. I recheck every step of the configuration and everything seems ok. 
With permission issue what do you mean: files permissions in apache environment or other permissions?

Looking at the Sugarcrm Log In correspondence of the PHP error I find this errors:

• Warning: Multiple links found for relationship users_team within module Users
• Unable to determine best appropriate link for relationship users_team

I've already tried to repair teams several times but with no luck.

Thanks a lot!

Regards,

HI André,

what folder of the cache directory: It's a production release and I know that there is something not to cancel.

Could you tell me?

Thank you in advance.

Hi Federico - we once faced this issue and fixed it this way:

We added br to HTTP_ACCEPT_ENCODING on PROD which was missing on PROD but present on DEV.

This my help.

Good Luck. C.

HI all again, for the REST issue I found the problem that was located in the client library because I didn't set the Application: Json header (In the previous version of the library found in the Sugar documentation there wasn't).

So this solve the problem. But the language error still stay. I've deleted all the cache folder and made a QRR. The italian labels are used in the English language and in the ITalian language only placeholder are shown.

Any suggestion?
Thanks in advance.
