Hi,
I installed the updated version of your theme, and now everthing seems to work fine. If any other problem occurs, I will contact you via Email. Thank you so much for your support.
One more question so far:
Is it possible to change the size of the featured image of an article? It would be great when the width of the image above the post would have quite the same size as the post, and would not appear as a small image.
Thanks in advance!
Daniel
