Hello,
I’m trying to import the new contract but the process abort with the following error:

NOTICE: [8] Undefined property: Account::$SecurityGroups on line 273 in file /var/www/suitecrm/data/Relationships/M2MRelationship.php

I’ve created two group in the CRM. I’ve installed the new version Version 7.10.9
Sugar Version 6.5.25 (Build 344)

Can someone tell me What is the problem?

Thanks

Hello,

It seems on your server it shows display logs true that’s why it fails to return value in ajax.
You should not display warnings on screen.
