The error above indicates that you have the Virtuemart 2 profile plugin installed and enabled. Do you have Virtuemart 2 installed? If not, you should not enable that plugin. Similarly, if you enabled the JomSocial, Community Builder, Kunena, or other profile plugins, but don't have those extensions installed, you should not enable those plugins.
