Well, the error is caused by a plugin you are using. The only way to fix it is to disable the plugin or fix the plugin. We don't know what plugin it is, nor do we know the code (obviously), so it is very hard to tell you what is wrong. Well, what is wrong is that they are calling for a column called "field" in the table "vbs_ticket_post" and it isn't there. So, you need to figure out why it isn't there and then add it or get rid of the call to that field if it is no longer needed (because you deleted a plugin).
