Recently I encountered a strange problem with my Drupal installation.
In the visibility section of my block settings, “Content type” is shown twice. There seems to be a difference between the two since one it titled “Content types” and the other “Content Type”. See the screenshot below.
I suspect this has to do something with a recently installed module but since I installed quite a few in the last week, I have no idea which one.
Any suggestions what could cause this problem? Not only is it pretty annoying, it also prevents blocks from showing up on a certain node type.
