"content cannot be blank" error


New Member
Hey, i can't send email campaigns. when i try to i don't see the full editor i just see a blank textarea input without any options... and when i try to click "save and next", then everything i inputted there disappears and it gives me an error "content cannot be blank". what am i doing wrong?

Also, i have a notification at the top that says :
  • The extension "CKeditor" needs updating from version 1.0 to version 1.2.3!
Is this connected? how do i update it?

Thanks for the Help!
