Unable to post on forum

Anyone having issues posting on their forum. I tried as admin and as a user and neither worked. And I tried using my computer and my phone. My computer gave me a message that said' you're unable to publish this post, contact site owner'. My cell phone just kept spinning. My site is: www.chowdowngreatlakes.com any suggestions to fix would be greatly appreciated. I did submit a ticket but would love to fix it tonight!
