I have a problem, appearing when blog post contain images with .GIF / .PNG format.
Here is my blog: http://demo.halsafitness.se/
It works fine in the archive view, but when I try to click in to the post with .PNG file in it, everything gets white. http://demo.halsafitness.se/2016/01/13/new-post-with-png/
Anyone know what could cause this?
