Members cannot start a new post in a channel

This was actually the solution to the issue although I didn't have to add anyone, just turn on Moderation for a few minutes and then turn it off and the funny part is I remembered that I had actually done that on one of the channels but I didn't associate that action to it fixing the issue until this morning.

ChrisWebbTechI didn't try that, but I think I have figured out the solution if not the actual issue.   I created a test team and used the exact same settings and it worked fine.

I went back into my problem team and reset the General settings to owner only and did some testing.   I found that of the members that were added yesterday, none of the ones who tested for me were able to add new posts to either of those channels.

However new members that I added today were able to create new posts in those channels.   I am now testing with a couple of yesterdays members.   I have removed them and then re-added.  We will see what happens.
