Hello Francis,
It looks like when EasyBlog tries to save the post, Joomla is throwing a 403 - Forbidden error as you can see here,
http://take.ms/iOx0b
This is normally caused by firewall plugins / security plugins which is reporting a false safe alarm. I can't access
http://lafactory.com/administrator/ to check which plugins are causing this as accessing the back end only displays this,

Do you have such plugins installed? If you want me to check on this, please provide us with the access to the administration area.
