workflow and cron don't work

hi everybody

I'm trying to set up a workflow also setting up cron.

When I run the cron does not send the email, so I went to check the error log for apache.
These are the lines of the error:

[Mon Jan 21 23:51:30 2013] [error] [client 192.168.1.92] File does not exist: /var/www/vte/modules/.js, referer: http://192.168.1.200/vte/index.php?module=com_vtiger_workflow&action=editworkflow&workflow_id=4&return_url=%2Fvte%2Findex.php%3Fdescription%3Dtest%26execution_condition%3DON_EVERY_SAVE%26module_name%3DAccounts%26save_type%3Dedit%26workflow_id%3D4%26conditions%3D%26action%3Dsaveworkflow%26module%3Dcom_vtiger_workflow
