Heya!

Currently I am working on a SilverStripe project, and everything seems to be running smooth.
But then things changed.. This morning I tried to login and I got the message that an error occured.
Running in development mode gave the following errormessage:

[User Error] Couldn't run query: SELECT "SiteTree_Live"."ClassName", "SiteTree_Live"."Created", "SiteTree_Live"."LastEdited", "SiteTree_Live"."URLSegment", "SiteTree_Live"."Title", "SiteTree_Live"."MenuTitle", "SiteTree_Live"."Content", "SiteTree_Live"."MetaTitle", "SiteTree_Live"."MetaDescription", "SiteTree_Live"."MetaKeywords", "SiteTree_Live"."ExtraMeta", "SiteTree_Live"."ShowInMenus", "SiteTree_Live"."ShowInSearch", "SiteTree_Live"."HomepageForDomain", "SiteTree_Live"."ProvideComments", "SiteTree_Live"."Sort", "SiteTree_Live"."HasBrokenFile", "SiteTree_Live"."HasBrokenLink", "SiteTree_Live"."Status", "SiteTree_Live"."ReportClass", "SiteTree_Live"."CanViewType", "SiteTree_Live"."CanEditType", "SiteTree_Live"."ToDo", "SiteTree_Live"."Version", "SiteTree_Live"."ParentID",

I checked mysql on empty classnames, some where found but got their proper classname.
Anyone has any suggestions on how to overcome this error and get the login back to working again?

Thnx in advance!
