There probably is a journal for which you have activated entry controls. You need to activate the develope (or debug) mode, > go to your different journal and open them one by one > check in the "Advanced Settings" if the "Allowed accounts" field is empty or populated with specific accounts. If populated, try removing the accounts in that field and it should work.

PS: there surely is a good reason why the account control would be activated. So handle with care :)
