Sorry but I cannot reproduce the problem.
Please be very specific about what file(s) you downloaded and where you downloaded them from and what steps you took to install.
I just tested the mojoportal-2-3-5-8-b-mssql-net35-deploymentfiles.zip package on a new clean installation and it worked fine and did not exhibit the problem you describe. That is a pre-compiled deployment package meant for production deployment. Many others have upgraded to the latest version and no-one else has reported this problem.
If you use the source code you should get the very latest version rather than the version that corresponds to the 2.3.5.8 release. It is best to get the latest code from our source code repository.
Hope it helps,
Joe
