I used to have the AJAX-like popup screen whenever I clicked on the image of the Grid format. Whenever I clicked on an image link on the grid, I got something like this (the image below is just an example so you will know what I am blathering about):
Ok, now back to my own screen. Here's what my screen looks like before I click on an image link...I then click on "1. Take the Test", and I used to get a nice popup AJAX-like window with the activities of Section1 of my Moodle coursepage displayed while the rest of the screen is dramatically dimmed.
..and then I get this which is correct, except that I don't see my splash screen anymore. So no more "popup window where the rest of the screen beyond the borders of the splash screen is dimmed" thingy. Somewhere along the way I lost it. I am using Moodle 2.5 with the latest, as for now, Grid format course format ($plugin->version = 2013110503).
Any ideas why this is happening and how I 'managed' to lose my splash screens?
