Hi esack,
If you want to hide editor when page load, please do not use 'display:none', try the code below, it will not get the error.

<input type="button" id="button2" onclick="show()" value="ShowEditor" />
<div id="div1" style="visibility: hidden">
<CE:Editor ID="editor1" runat="server">
</CE:Editor>
</div>
</form>
</body>
</html>
<script>
function set()
{
var editor1=document.getElementById("<%= editor1.ClientID %>");
editor1.SetHTML(" ");
//if SetHTML("") can not clean the text, tyr add a space, like SetHTML(" ")
}
function show()
{
var div1=document.getElementById("div1");
div1.style.visibility="visible"
}
</script>
