Cathal,
You said "I still can't recreate it". What are you trying to recreate?
Yes, the debug is set to false. This is the default setting and I have not changed it.
I read http://www.inventua.com/blogs.content?EntryID=5 . Some of it is over my head. Which folder is webresource.axd suppose to reside? I downloaded the webresource.axd from that link and put it into the root folder of my DNN site. That did not fix the problem.
No, I haven't made any changes to the default install. In fact, the hoster installed http://aspdotnetnukehost.com and I don't have an account with this hoster so I don't have access to the files. From this DNN site, I created a child portal: http://aspdotnetnukehost.com/test , with nothing added, and it still has the log-out bug.
I have an account with WebHost4Life and used their auto-installer to install Http://site343.mysite4now.com/curt/dnn and then created a test child portal Http://site343.mysite4now.com/curt/dnn/test , which also has the log-out bug. However, I did not change the default install. These are bare-bone, default, template DNN sites. I checked the web.config file for this install and the debug is set to false.
Because these bugs appear with default installs of DNN, I'm surprised that others have not posted about this bug on forums.
