No Save Button on WYSIWYG1 user found helpful
I noticed this is a different editor called CKEditor then the one I had before on a different theme. I still can't find the save.
When you switch to the default Elemental theme, do you still have the issue?
I found that I get this error because I loaded jquery in my template header. ("<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
") Deleting this line solved the problem.
I did not have this problem in other website's untill now. So I think it is a combination of the latest version of concrete5 and the new editor resulting in JS conflicts.
