I have to say that I am having a similar problem to genej101.
I have tried using both the Visual and the Code view to edit some posts, without much success. I say without much success because I have applied a number of elements (styles, font colours etc) that have shown fine in the Visual and Code views. When I have gone to save the post all of this has been stripped out, just leaving (relatively) plain text. Blockquotes, bold, italics etc seem to be working OK. I’ve followed the examples on applying styles given in the Codex, none of this has helped.
Why would it be doing this?
Am using WP 2.2.2
Thanks in advance
