Admin Login not possible "is not a valid module name."

[bachmama]

Hello,

we tried to log in the backend but as soon as the admin url is clicked we get the message "is not a valid module name."

So no access possible. we´re quite puzzled, we haven´t changed anything the last days. Shop Version is 1.6.1.x, problem is i cannot even see the login page to give you the exact version.

anyone knows what this is about? thank you very much for any available hint.

Looks like the solution is to update config/xml/must_have_modules_list.xml

add the name of your backoffice module by changing

 <name><![CDATA[]]></name><displayName><![CDATA[Store Manager for PrestaShop]]></displayName>

to 

<name><![CDATA[backoffice]]></name><displayName><![CDATA[Store Manager for PrestaShop]]></displayName>

(that's assuming your backoffice module is called 'backoffice')

is backoffice the default name? Not that i know we would have changed anything...or is there a way to figure out on files/directories on the server?

Thank you for you help! Gonna pick that apart tomorrow morning.
