I have two textareas that I load when the page loads, these two textareas are in the same table row. My tinyMCE looks like this
tinyMCE.init({
Give them different ids. Tinymce editor id is equal to the textareas id; if no textarea id is present "content" is used as default. In your case for both textareas. Because there is already a tinymce editor with id "content" when the second textarea is being converted into a tinymce editor instance - it fails.
