B1UP 2016.11 release have a bug that prevent it from starting properly in Browser Access. At startup you get an unknown error (Object ref. not set to an instance).
We have released a hotfix 2016.11 HF1 (www.boyum-it.com/sbo) to resolve the issue are there are unfortunately no workaround and update our test-scripts so it should not happen in furture releases.
NB: Normal client work fine so no need to upgrade if you do not use browser access.
