One of the most common questions people have to questions people ask are things like
AGOL or Enterprise
Versions
ArcMAP or ArcGIS Pro
Data source i.e. shapefile, .mdb, .fdb, SDE database etc...
Quite often the answers will be specific to where the issue is coming from.
I would suggest having a Set of questions the asker can fill out first, for this and almost every other group in the forums, that would answer these question.
Not mandatory but the first question could be something asking if they want to fill out configuration details to help with their question.
