Login issue

Afternoon all, I have a lovely problem. The primary reason for my site is eCommerce site (http://www.belovedbundles.com.au). When I installed Easyblogger today all went well or so I thought until I tried to "Login" in the front end to purchase stuff etc. Backend login's still work (username/password is still good) also another fun fact is when I register a new user it will create that user and I will be logged on. But if I log out and try and get back on it fails.
The eCommerce platform is Aceshop 2.0.0 using Opencart 1.5.4.1
