Community Answers No access

Hi all i have just literally installed Community answers on my site which is using Jomsocial..

The component is working fine for users logged in via joomla login but if i login using the jomsocial facebook connect i cannot read an of the questions or anything i get this error >>> You are not authorised to view this resource.

THis error is shown in the breadcrumb of joomla.

I have checked the permission settings for the component and all the categories and are are set Registered User + admin and + super user

The read level is set to Public.

I also noticed that there is alot of styling that conflicts with my sites styling already. :( Is there any easy way to rectofy this other than going through all the css etc
