I installed phocadocument 3.0
I have a category and sub categories.
I put 2 articles in my subcategory which are counted well.
My problem I cannot open the file...

Did you set this categories in Phoca Documentation Options?I have a category and sub categories.

No! Are the articles 'published' and set to 'public'?Question: Do have to make also an new menuentry for that article?
