First post but i am sure there will be many more to follow.
in the location, site administration> User> Define Roles, when editing there should be a table displaying the various permission options 'not set', 'Allow', 'Prevent' and 'Prohibit', however, the only one that is displayed is 'Allow' (please see bellow). so far this is the only thing I have found to be missing but I am concerned there may be more.
I have been able to locate the problem to the sql database but can't find the table responsible for the table. I have found a working backup and am wondering if I can salvage the required sql table from it and import it into my later version.
The problem seemed to have arisen from a site migration (I did backup, but this has been noticed further down the line).
If any one could shed some light on how to rectify this, it would be much appreciated.
