Yes, OG tags should always be present, that's normal.
However, on my site, when I disable "avatar as icon", the og:image flips from the profile icon to the default K icon.
Retina icons shouldn't be profile pics however, they're mainly for if you bookmark the page on your iThing so you get a Known icon rather than the default.
Kudos for hiring Tom Hardy in Venom. It makes it much easier for guys to convince their Mrs to see a super hero movie for date night.
I haven't been able to replicate - I can connect to twitter (latest build of the plugin, and latest known from github).
Server is PHP 7 / Apache2.
When you hit the connect to twitter button, do you get forwarded to twitter and are asked to authorise the app there?
I have a bunch of .pot gettext files which need to be translated. Are there any (online) tools to make it easy for people to submit translations for strings? I seem to remember the Ubuntu project used to have something, but that doesn't *seem* to be the case any more...
Yeah, the open graph plugin was something I wrote a while ago but the code was essentially merged into core and so that plugin is deprecated.
Anything in your logs?
I'd argue that if this only shows when "Avatar as icon" is set, then this isn't a bug and things are behaving as expected...
