I noticed today that my editor for new posts looks like the following image. The buttons work fine, and the tooltips show up as expected but the icons appear to be missing.
Any suggestions for how to fix this?
I see that addon developers have difficulty to add buttons to the 'insert' redactor dropdown. Developers need to add buttons to the main redactor bar, which clutters the bar over multiple lines with both essential as non-essential (but still handy) buttons.
I am not sure if that's why @Chris...
