@andsome:
Sounds like you pasted HTML code in the regular Auctiva editor instead of in the HTML editor.
Go in to your saved listing and look at the editor. If it's HTML code that you see while you're NOT in the HTML editor, then indeed you have code where you should have regular text. Select All (ctrl-A) and CUT (ctrl-X) so that the window is then EMPTY. Switch to the HTML editor and Select All there then PASTE (ctrl-V) the contents of the clipboard (the HTML code that you just CUT from the other editor) in to the HTML editor.
Switch back to the regular editor and you should see your text, and not HTML code.
Hope this helps,
Richard
