I am pretty sure that I understand the function of this plugin, add OG tags in the header so that facebook will grab the correct (the featured image) of a post when sharing?
Many months ago I initially installed version 1.1.5 of this azurecurve plugin and it never worked, facebook grabbed the header image. I installed it on a classicpress site and a wordpress 4.9 site with different themes and neither ever worked.
I tried it again this morning on this classicpress site:
ClassicPress 1.2.0 running “Mission News” theme.
Running PHP version: 7.0.33
Still the header image was showing up when sharing posts at facebook - the OG image tag showed content=" "
(I had the fallback image turned off because I was getting header images)
I updated to the newest version 1.3.3 and the site crashed.
Does anyone have any ideas?
