RenderArtisteerBlockContentDivs is not a property, that stuff is controlled by theme.skin file
Most likely problem is it is failing to load you layout.master file for some reason or it is failing to apply the theme.skin file.
Check the mojoPortal log under Administration > System Log for possible clues to the problem.
You did not mention operating system or .NET version
You published from VS, did you start with actual source code or you re-published our deployment files (which is a bad idea and could be the cause of the problem).
When deploying from source code you compiled I recommend deploy to local file system first and review the files before uploading to a hosted environment.
