User Manual Entries not accessible if administrative changes disabled

[bengreenbank]

Hi

We currently use the 'allowAdminChanges' => false, option in general.php in our Staging and Production environments. However when we try to access the User manual entries (admin/usermanual), it seems to redirect to admin/settings/plugins/usermanual instead and give a 'administrative changes are not allowed in this environment' error.

The user manual entries are still accessible on dev environments.

Many thanks for your help
