Today, I logged into my moodle site (on a shared hosting server) and noticed that the Gear for Turn Editing On is just a square box. I also noticed that when I click on a Topic, it doesn't open that topic (used to open it in single topic view.
I was using Chrome, so I switched to FireFox and am able to open just a single topic, bu all of the icons for editing etc are just a square box. (like a checkbox). The activity/resource icons are fine.
I was trying to add files to my course (in different topics). I added a pdf to my first topic in a new course and it worked fine. When I tried to add a pdf to my second topic, it failed to write to disk. Now I cannot upload any files.
Could it be a folder permissions issue? Where do I start looking? What should the perms be? I am fairly new to moodle.
