I've got an installation of SugarCRM Pro in my own server and today I migrate from 126.96.36.199 to 7.9.1.
Language different from English are broken but the very important thing is that in some cases, using web services via Rest V10 give me a 500 error and the error, on sugar side is PHP Fatal error: Call to a member function retrieveSettings() on null in /var/www/crm/modules/Administration/Administration.php on line 368.
In some calls, external web services work good in other not.
Have you some hints for investigate in the right place?
Thank you very much for your help in advance.
