Some errors on the dkan_sitewide.module

Hello everybody,
I finished the install and I have some errors on the dkan_sitewide.module

Notice: Undefined index: dkan in dkan_sitewide_update_status_alter() (line 201 of /var/www/html/dkan/profiles/dkan/modules/dkan/dkan_sitewide/dkan_sitewide.module).

Notice: Undefined index: existing_major in dkan_sitewide_update_status_alter() (line 216 of /var/www/html/dkan/profiles/dkan/modules/dkan/dkan_sitewide/dkan_sitewide.module).

Notice: Undefined index: existing_major in dkan_sitewide_update_status_alter() (line 216 of /var/www/html/dkan/profiles/dkan/modules/dkan/dkan_sitewide/dkan_sitewide.module).

Notice: Undefined index: existing_version in dkan_sitewide_update_status_alter() (line 241 of /var/www/html/dkan/profiles/dkan/modules/dkan/dkan_sitewide/dkan_sitewide.module).

I think there errors are minor because I have the possibility to visit the new website.

Have you got an idea to resolve that ?

Best regards
Laurent
