Important Notes:

Showing a Log to a user connected far away from the server user might create :

A connection issue due to the poor connection and the huge amount of Logs coming from far away.
Latency issue if user has limited internet connection.

We recommend disabling ‘Print UE4 Log in Browser Console’ in your config if it is not needed.

Now, you are ready to get and save your Logs from your Browser Console !
