Fixed on master thanks for reporting. https://github.com/NodeBB/NodeBB/issues/3820

@a_5mith said: hljs Im using the default nodebb composer. I think I've fixed the problem, temporarily. I manage to remove those long text (http://pastebin.com/wQktbjtT) and it fixed the problem. The long text string seems to break nodebb. I test posting the same string again, but nodebb wont allow as it is longer than 32767 character. Thanks for your time @a_5mith
