Hello,
We are running Moodle 2.6.2 (20140310) with Essential 2.7 (2014020300). I just pulled a fresh copy of Essential from Github.
I am encountering two issues.
1) Drag and drop with blocks does not work. When the page first loads the cross-hairs appear on the blocks, but once the page fully loads those disappear. The only way to move the blocks then is through the configure options/menu.
2) The turn editing off button does not work once the page fully loads. It is possible to get to do so right after refreshing the page, but once the drag and drop notice appears, the button is not clickable.
Here is a video illustrating these issues.
The drag and drop cross-hairs function as expected within the main course area. It is possible to drag and drop resources, activities and labels to reorder them.
Any assistance would be greatly appreciated. Thank you!
