Hi Paul,
I am sorry for the late reply.
Em, look like the Joomla admin access and the ftp account that you've provided failed to authenticate me
Anyway, regarding your issue, its a known issue where the stream setting in the blog app not being respected. We've fixed the issue internally. For the quick fix, can you download the attached 'blog.php' file and copy this php file to folder 'JOOMLA/media/com_easysocial/apps/user/blog/' and overwrite the existing blog.php
Remember to backup the original file first before you overwrite with the attached one.
Once you've patch the file, you can now turn off the updates stream from your blog apps from your EasySocial backend under application page.
Hope this help and have a nice day
