[resolved] Can´t delete the Trash

I have installed 0.9.6.2 as a new Installation, then imported the database of the 0.9.6.1p2 and everything is fine. After a couple of work the button "empty trash" disappeared.

Then i have tried to setup an new role with the qualification to empty the trash but the following message appears:
"« MODx Parse Error »
MODx encountered the following error while attempting to parse the requested resource:
« Execution of a query to the database failed - Unknown column ’empty_trash’ in ’field list’ »
SQL: INSERT INTO `xxxx`.`yyyy_user_roles`

Can you help me?

You must run upgrade after importing the database.

Thank you very much and best wishes from Hamburg/Germany, now it works fine.
