HTML INSERTS
As described here in the
HTML Inserts section
If the page starts with < sumbol and ends with > it is considered to be HTML without formatters.
"To define an entire page as HTML begin the page text with < symbol and end it with >. There should be no line breaks or spaces after >.
Do not put <html>, <head> or <body> tags inside your page."
Please make a note of it.
You can correct this by introducing a space on the first line.
