I've just finished an upgrade from one of the early version 2's (pre auto upgrade feature). All blogs are working fine, but when the admin user attempts to login the following error is returned:
'You don’t have permission to view this blog. Please contact the system administrator.'
It is a Wordpress error page, not an apache or php error etc.
'?c=5' is also appended to the URL.
A google of the error message amazingly doesn't return a single result :(
Other users can login and access their dashboards ok.
Any ideas?
