Hi there,

I have an alleged error in the statistics: The following message appears during the evaluation:

java.lang.IllegalStateException: The viewing session is not available or has expired.

Is there a solution for this?

Thanks.

1. Which version of OpenEMM do you use?
2.Which statistics do you mean, please provide click path.
3. In which form does the error message show up and is this the complete message?

Was the same issue today, while entering to admin panel not from https, but from http (not secured protocol).
After re-entered in https - mode the error gone.
