Hello Jereme,
I am really sorry for the delay of this reply as it is a weekend for us here.
I have tried to access in your Joomla backend and FTP access but it seems like not working for me.
May i know are you try publish the blog post from backend?
If yes, can you download my attachment file and replace in this file and see how it goes?
JoomlaFolder\components\com_easyblog\helpers\router.php
because this should fix it in latest version of Easyblog.
