My site is viewed fine before i log in but as soon as I am logged in as webmaster the frontpage is blank so i have to manually access admin palen via /xoops/admin.php takes me to the correct place. I have looked every where through my settings and cant think of what could have caused this. I don't think it has anything to do with the files just the settings. Any ideas what i might have set wrong and how to change it to somthing appropriate?
Thanks LiamMac.

One of your blocks is probably causing it. Look at the ones that are visible to the webmaster group.
