Not Authorized error v1.4.5

Hi I upgraded from 1.3.3 to 1.4.5 no problems on j1.5.26
I then did a migration to j2.5 and setup EB 1.4.5 then migrated my DB
Now all the events are showing as not authorized.
Is there some ACL setting as as the events are set to public access?
Thanks

Solved it - the events need to be all individually re-saved

The reason is because In Joomla 1.5, the Public access level has ID = 0 but In Joomla 2.5, the Public access level has ID = 1. That's the reason you have to re-save the events .
