Hello, I have an issue with Cornerstone.
I receive this message on white screen:
"Warning: require_once(/home/host1432403/the-dialogue.com/htdocs/test/wp-content/plugins/cornerstone/includes/shortcodes/promo.php): failed to open stream: Слишком много открытых файлов in /home/host1432403/the-dialogue.com/htdocs/test/wp-content/plugins/cornerstone/includes/classes/classic/elements/class-element-orchestrator.php on line 123
Fatal error: require_once(): Failed opening required ‘/home/host1432403/the-dialogue.com/htdocs/test/wp-content/plugins/cornerstone/includes/shortcodes/promo.php’ (include_path=’.:/usr/local/php/php-5.4/lib/php’) in /home/host1432403/the-dialogue.com/htdocs/test/wp-content/plugins/cornerstone/includes/classes/classic/elements/class-element-orchestrator.php on line 123"
There’s a thread that indicates that reinstalling cornerstone helps. It actually does, but the solution is temporary. A couple of hours hence it breaks again.
I believe the problem might be with compatibility of cornerstone and ACF plugin.
And there’s strange issue: I have 2 absolutely similar instances of WP and X theme on different servers: above mentioned problem persists only on one of the instances, when the other is fine.
How can it be fixed?
