Well, everything was just fine till I had to add new article and to show it in the Content slide module. I had exactly 3 articles in the category that is assigned to the slide module. But, category was assigned to module after all of the 3 articles were created. Now, I added a new one, but nothing changed in the slide module. There are still old 3 articles, and when I try to slide in the hope that I’ll see my new article nothing happens. And module is configured to show 3 articles at once, and maximum of 10 articles through the sliding. I purged the cache of the modules and that didn’t help. Is there any logical explanation for this or I’m doing something totally wrong. Thanks in advance for Your answer.
EDIT: In the meantime I found the solution. Problem was caching. I turn the caching off and everything was fine. I hope that I’ve helped someone.
