I am quite new to Qlik Sense and I am facing folowing issue:
A couple days ago the engine of our Qlik Sense installation stopped. The first thing I did was to check Qlik Sense Service to see if one of them was no longer running, but that was not the case as all of them were working just fine.
Then I searched in this forum just in case I was able to find a similar issue, and I found this one:
Re: Engine Stopped, and I can't find the log folder
In the QMC, Engines, edit the node and be sure that the Audit activity log level is not OFF. You will find this check box in the Logging menu. You can do the same with Proxies, Schedulers and Repositories.
