Hello Klas,
Thank you for your reply.
You were right (again ;)). The Importer plugin was up to date but not Seblod component (3.8.1).
Updating to the last version of Seblod (3.8.4) solved the problem.
One more question: when User Bridge is enabled, the import process create 2 articles with the same name for each imported user.
In the 2 articles related to one user, the ::cck::id::/cck:: is the same. So I gess I could remove one copy without breaking anything. Could you confirm?
When User Bridge is disabled, no article is created.
Could you please explain a bit what are the advantages of enabling User Bridge?
Regards
Simon
