I wrote a page today (not a post) that I wanted only to be accessible by level 3 members. So, in the drop down box in page edit window I chose that it would be viewable by Level 3 members. This was a page agreeing to our website guidelines, so wanted everyone to just comment at the bottom of the page that they read it.
When I published it, the comments template was not there. I double checked all of my wordpress comments settings and made sure the page had comments enabled, as well as checked my theme to make sure it was using the standard wordpress comments template tag.
When I removed the s2member access restriction, the comments template did show as it is supposed to.
So, I don't know if maybe this is bug or something I missed in s2member settings, but thought I would see if anyone had any ideas here.
