I tried to install Dragmath in the HTML editor (Moodle 1.9.4), so I followed the instructions in the documentation page
I'm working with Linux Ubuntu. I unzipped the file in the moodle folder and it created a folder Lib(2) with the editor and Dragmath folders inside. I inserted the line 'insertdragmath' => 'em.icon.dragmath.gif, in adminlib.php and it didn't work.
Next, I backed up the folder named Editor (which is in the lib folder), and manually copied DragMath and Editor folders (which were in the lib(2) folder) into the lib folder. What I got is the HTML editor with no icons,no dragmath and disfunctional.
Any help? Please,
