You are right. You shouldn’t be able to do that, but I would imagine you were the first to ever try it! Probably wouldn’t come up much as usability issue, but maybe put up a TRAC ticket:
I’m having a similar problem in that I may have deleted the Key Master user, as when I log in as ‘admin’ (which was my Key Master) I don’t get he Admin link to go to the Dashboard.
It happened after I deleted a Key Master user, although i thought that admin was still a key master. However, I’m getting all sorts of problems with not being able to log back in after changing the password. It seems to to ‘take.’
This falls under the same problem of accidentally demoting yourself below keymaster to admin (some people try it to remove the somewhat silly title from displaying)
two ways to fix it manually and get back keymaster status:
the technical way:
the easier way (but might reset other data, not certain)
I guess I’ll try adding it to trac
