I updated to the latest version of WP and Social. Once editing a post, or trying to publish or save a post in progress (or just about any other admin function), I would get Error code: ERR_EMPTY_RESPONSE, or 404 or a 500 error. This would happen intermittently (about 80% of the time).
I called my hosting provider, and checked just about everything I could find to no avail. It was only after disabling the Social plugin that everything started to function normally. It took down both of my WP sites.
I can reproduce this issue by simply reactivating the plugin.
I love this plugin. Please look into fixing this.
