I have tried changing the schema logo many time all to no avail, the default EB logo stays put, more also Google is not even seeing the default schema logo but joomla logo, I don't know why. Maybe the screenshot would help you understand what I mean.
Secondly, according to the settings to use first picture as post cover, this settings doesn't apply to quick post, I don't know why?
Lastly, from the front page listing, how is it possible to approve post from the backend but disable it from appearing on frontpage listing but it can be on authors profile once it's approved
