I have checked my settings in my account and it says to use the Rich Text Editor.
Ive tested this issue in Google Chrome, Firefox, Opera, and IE and get the same results in all 4.
I have tested Creating a new topic, and replying to old ones by clicking more options.
This is a strange issue and it seems as though im the only one experiencing this issue. Using xenforo.com i have the Rich Text editor so i don't understand why its only missing on my website :?
