@dituyi. Thanks for posting. Could you provide a link so that I can see what you mean? I am more than happy to help you. However I am out of town and away from the office. So, I am limited in how much I can help until Monday when I get back.
However from what you explain it may just be an issue of your wysiwyg editor adding extra tags. That is just an educated guess since I would need more info from you, and possibly temporary admoin access to your site.
If you don’t want to post a link to your site on the forum, that’s fine. Just email me.
