well, just hope the author willing to fix it on the next release.
The latest version is compatible with Opera. If you still notice problems with Opera, please let know through our contact page of forum which Opera version gives problems
The errors are mostly located on attributes that didn't use quotation mark, while the rest caused by '/' wasn't placed on self-closing tag.
