Hi Hari / Joe, I have only been using DNN for a couple of weeks and have already come across this bug. I found references to it dating back to 2006.

From the above links it is clear that there is a very big bug that affects many users. If you don't get it you are lucky but that could change.
In my case the user gets logged out as soon as they click on the standard store module page of a child portal.
If a user with the same name is created in the parent portal the problem immediately dissappears.
Delete the corresponding user in the parent portal and the problem is back.
I am now running 4.9.5.
I would appreciate it if someone can tell me if this bug is going to be fixed or if it has been swept under the carpet.
It appears to me that if one wishes to run DNN reliably then you shouldnt use child portals at all.
