I just upgraded to EasySocial v1.3.30 and now the Author Information has returned. However, when I check the setting above, it's still set to NO, but the Author Information still shows.
I cleared all caches and this did not help. I tried turning the setting ON then saving, then back OFF again and saving. Did not work. I finally had to totally disable the EasySocial - Content plugin to remove the author info. But I liked being able to add activity, points and badges integration with EasySocial.
Any ideas?
