The Flarum site forums.trisul.org was working fine.
I added a new post and now the site wont respond. Not just the new post but the entire site. I got this message in error.log
[Wed Jul 19 11:14:15.922967 2017] [:error] [pid 25111] [client 103.199.147.33:54415] PHP Catchable fatal error: Argument 1 passed to Flarum\Event\ConfigureFormatterRenderer::construct() must be an instance of s9e\TextFormatter\Renderer, instance of PHP_Incomplete_Class given, called in /var/www/flarum/vendor/flarum/core/src/Formatter/Formatter.php on line 77 and defined in /var/www/flarum/vendor/flarum/core/src/Event/ConfigureFormatterRenderer.php on line 37
Can anyone help?
Thanks,
Vivek
EDIT: Update to the latest version. Started, restarted apache. Still the same error.
