I am trying to develop a theme based on the base theme. Now in the admin pages, e.g. a part of page at http://localhost/moodle/course/edit.php is shown in the picture below, the core images are not being shown.
I checked in the firefox inspector, and it says "Could not load image", as shown in the following screenshot.
But when I changed the value of src attribute of the <img> from http://localhost/moodle/theme/image.php?theme=testy&component=core&image=req (where testy is my theme) to http://localhost/moodle/theme/image.php?theme=base&component=core&image=req, it started working. I also checked in moodle/pix directory and the image req.gif is very much there.
What might be the reason behind this? What should I do about it?
