Umm...thread can't be posted

[KiLLWiT]

Whenever I try to post a thread, i get the following error:
The message you have entered is too short. Please lengthen your message to at least 1 characters.
yet my message is about 10 lines long. :S I'm using vBulletin 3.8, and I've tried disabling products, but no luck. help please?

Do both of these and see if it helps:

Create a new style with no parent - Styles & Templates > Style Manager > Add New Style > no parent - then browse the site using that totally default vbulletin style - do you still have the same problem?

If it is still happening, then try disabling your plugins and see if you still have this problem.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

define('DISABLE_HOOKS', true);
