Looks like the default value (open up the irite interface and look at the default value field).
it will be: <%= Replace((WADANeilgww_adminBB1.Fields.Item("content").Value)&"", """", """) %>
See where it says Replace...That replaces Quotes with "... which is the problem you are having. This is necessary when working with input type="text" fields, but not with iRite.
Update it to:
<%= WADANeilgww_adminBB1.Fields.Item("content").Value %>
