Error after upgrading template to 2.16

I get this error after upgrading the template Gk_finance_business to 2.16.

Warning: str_repeat() [function.str-repeat]: Second argument has to be greater than or equal to 0 in /nfs/c04/h01/mnt/59867/domains/upgradebeachcamp.se/html/administrator/components/com_menus/helpers/menus.php on line 184

Thats a core joomla file, perhaps upgrade wasn't successful, try downloading joomla package from joomla.org and upload administrator folder again overwriting files / folders.

Also try repairing database from extension manager.

It was a problem with the upgrade package to my Joomla site. That affected the Menu table in the database.
