Group members unable to access Group Discussions intermittently
Using Jamroom
LOL, 'intermittently' is fine when accompanied by steps to reproduce it. Its the "something is wrong somewhere sometimes" overtones of 'intermittently' that make it a daunting task to even start to look for what and where then figure out the why.
I like strumlia's idea, that could be it. Another guess could be caching related but its a far stretch, thinking maybe they are seeing the page as cached for a user not allowed to access it. And another guess could be their session perhaps. Since its the first page they land on after having the session just start up fresh maybe the "ok" needed to show that page isn't there yet and will be fore the next page load, but because that page has now been cached for them they see the cache version of it.
just guesses though.
