Hello, I sent ou a ticket, after I went to articles/categories in Joomla, less K2. I found this:
1) I correctly have unchecket the category-import - result is I have only one category now : import data
so of course the site is not available.Where have these been gone?
2) I went through the articles and found a lot of articles, which are pictures
3) I found the emailadresses as articles from the users and commentators
4) I found comments from the commentators
5) posts from WP-mingel forum
6) events from WP - All-in-One Event Calendar by Timely, is deactivated
7) many copys of posts

How to solve this problem I could not find in forum and tickets
Thank you for help Andrea Lex
