hello
with the html plugin the opengraph works fine but not for index pages.
how can i setup a custom image to be used in the open graph for my index pages : gallery and news?
thanks

There is a plugin option named "site logo".

where do i find this plugin option?
so far the only thing i found is the option to select header logo, in my extensions there is no "site logo".

In the options of the html_meta_tags plugin.

thanks!
