[UPDATE]

I comment that line and now its works fine, but i dont like so mutch comment lines to undo bugs. So i need intel. What is $GLOBALS[‘server_unique_key’] and where ‘serverUniqueKey’ is filled? my ‘serverUniqueKey’ is emprty or null so the assing function dont fill anything.

code:
$sugar_smarty->assign(‘serverUniqueKey’, $GLOBALS[‘server_unique_key’]);

keep me posting

I’m also seeing

[WARN] Undefined index: server_unique_key

in my suitecrm.log (v. 7.10.9)

What is it referring to?
