Undefined property isMysqlUsed in object SB_ORM_SitePublishSettings;

This morning my SiteBuilder server not working.
Gave an error on the mysql password.
Reset the error when I access to SiteBuilder and click on the menu "site" to see the list of sites, this error appears:

Internal Sitebuilder error.
File: /usr/local/sitebuilder/include/Base/ORM/Object.php; Line: 189
Message: Undefined property isMysqlUsed in object SB_ORM_SitePublishSettings; Code: 0

I noticed which folders on the server sitebuilder have the date of this night as if they were created last night.
It is not that the system has made the upgrade to the new version SiteBuilder alone, and now no longer works?

Thank you for your help.
