Contact List Error Sugar 4.5.0h

[columbiacrm]

IN the past few days, I have been receiving this error message on the contacts list view.,

Warning: Invalid argument supplied for foreach() in /home/teamcba/public_html/sugar/include/utils.php on line 1279

Does anyone have an idea where this comes from. I have checked and cannot find a reference

Thank you

Gary

Did you customize a dropdown list of Contacts module? Doesn't it have any invalid key in it?
