a strange one, to be frank I haven't bothered deactivating any plugins as yet as it seems like it should be something else.
Unable to make an iFrame work in the text view on the editor. I loaded a previously published post with embedded video, it runs from from the preview without problem. If I copy the code in the editor, drop it in a new post, and preview it I get a blank space where the embed should be.
Code is unchanged, nothing has been stripped, by the editor, an exact copy but no output.
Any thoughts appreciated.
