Thanks Dimas. You pointed me in the right direction and I have found that the template works fine with Jomsocial except when I have the latest photo comments module in the template. I have everything working now except for the photo comments module which causes the problem when it is present.
Now here's the real mystery. The Photo Comments Module works perfectly on the site's Home Page???? How can that be? I have also tried removing all other modules from the Social Page and adding the Comments Module only; with the same negative results.
Your menu has own template / different template, make sure each template has all module positions.
Like your first issue, the social template doesnt have component code, so the jomsocial component wasnt show there :)
