OK point 1 is because in admin database language was changed.
I used SC for this, not sure if this is correct but is what is used for the simplified Chinese translation of pligg.
Anyway by default in the database the language is assigned with `category_lang` = 'en'. Therefore if categories were made before this was changed it breaks the category sorting.
Therefore for articles to show in the correct articles you need to make sure the setting in admin for databse language, and the attribute in Mysql for the articles matches.
2) i still have no solution for. 9.7 non
SEO friendly URLs do not seem to work, even after setting in admin.
story works fine as: http :// www .site.com/story.php?id=1
category however does not work and shows: http :// www .site.com/index.php?category=apple
