Thank you for letting me know. I had been seeing the error in the Google Analytics 4 system, but didn't know where it was occurring. A permission setting needed to be adjusted for the parent forum that oversees the Discuss The Soaps archives to allow people to read posts.
For every forum, there is a permission that allows people to see it, read it, post in it or reply to a post in it. The initial settings that triggered the error you saw only allowed people to see the forum. This has been corrected.
