Fatal error: Call to a member function getQuery() on a non-object Contact.php on line

[nat8100]

I have Sugar Version 5.2.0e (Build 5626) community edition, not sure how to find what apache server version I am using?

I am new to this and have made a rookie mistake, or several! I have this error on the home page and contacts page:

Fatal error: Call to a member function getQuery() on a non-object in /homepages/4/etc/htdocs/sugar/modules/Contacts/Contact.php on line 462

lines 461 and 462 are:

$this->load_relationship("user_sync");
$query_array=$this->user_sync->getQuery(true);

although I don't suppose this is the problem

I think the problem occured when upgrading from 5.2.0c to e

I have tried rebuilding relationships and repairing database etc. but to no avail.

I would greatly appreciate any help anyone can give me as it was all going so well before this!

Thank you

Seems recently , many people have confronted this problem. I have tried all I could, repair relationship, repair database. Just in vain. The error is still showing for the Home module and Contacts module.

I had the same problem.

I went to: http://MYINSTALLATION/index.php?modu...n&action=index

I repaired the relationships and everything else and it works fine now.
