Hi,
1. The 1st instance is seemingly working on my end. Can you please explain what do you mean by “article with more than 1 category, not found”?
I’m seeing results here: http://i.imgur.com/QE3O3Ho.jpg
Please also refer to this ticket: https://wp-dreams.com/forums/topic/mobile-image-not-responsive/
2. Which keywords do not work with the 2nd search instance? I’m getting results with random test words: http://i.imgur.com/vw7ODFb.png
Is this the right search instance, or am I looking at the wrong one? Can you please give me example words which should give results, so I can test them?
3. Where exactly is the 3rd instance placed? I can only see 2 shortcodes on the main page in the page source, but not the other search instance shortcode. Are you sure it was placed correctly?
