The above is using nginx 1.8.1 and php 7 php-fpm and i got the above and error got a php error report.
User error: Invalid placeholder (!url) in string: Missing the Video.js library. Please download Video.js and extract it into the %directory directory. in Drupal\Component\Render\FormattableMarkup::placeholderFormat() (line 240 of /srv/http/mywebsite/core/lib/Drupal/Component/Render/FormattableMarkup.php).
==============================
I test with https://simplytest.me/ drupal 8.0.5 with video.js modules install only. There no error.
Suspect php 7 or php-fpm that cause it. Can one confirm this.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Merged to the 8.x-1.x and 3.x branches.
Thanks!
