same as others.
Crayon Syntax Highlighter breaks my WordPress posting, but only on the backend. if i’m set up to use the visual editor, it’s broken. but … if i’m set up to use the text editor all is well and i can post from the back end without issues. if i click the tab for the visual editor, everything breaks.
however, i can still use the front end posting features of my theme.
i have tested this on the following:
Windows 7 and Chrome = broken as described above
Windows XP and IE 8 = broken as described above
OS X 10.9 and Chrome = broken as described above
OS X 10.9 and Safari = broken as described above
Ubuntu 14 LTS and Chrome = broken as described above
using WordPress 3.8.1
