Since I updated my WordPress to 3.6 I have been having trouble with my widget area. So, I added new calendar, when I tried to drag it into the sidebar I couldn't take it, it wasn't working at all. It was similar like when you block a layer in Photoshop, something like that. So, I tried to take out one of the current online widgets and it seems to be repeating a column with dotted lines, it really odd.
It this happen to anyone? Please help me out.
