Recently active problems in PBwiki tagged with html

I can't put an HTML on my wiki. It is from the Weather Channel and is called "Weather on your Website". I have tried it on three different computers and it doesnt work, it stops after I paste the HTML.

What has happened to the custom HTML facility in Pbwiki 2.0 settings page. My wiki is upgraded to platinum!

I'm trying to insert the full license HTML of my preferred Creative Commons License. If I put the html into a page, it shows up appropriately in the preview, but not when I actually save the page.

The actual content I'm trying to insert is a link containing an image, followed by some spans of text that contain links. If I view source on the saved page, I find a paragraph with an empty link (pointing to the correct place, but without the contained image), followed by the exact same link containing only a br tag. The second one is the *really* strange one, because that particular links only occurs once, at the beginning of the license wrapping the image, and a br tag *never* appears within a link.

I'm assuming that the html is being automatically cleaned by something, in the process stripping out all of the content of the license. Is there any way around this?

I want to make certain (external) links open in a new browser window or tab. To do so, I switch from my usually-preferred WYSIWYG editor to the "classic" wiki-markup editor and code the links using a target="_blank" ... -- works fine. I go back to working on the page with WYSIWYG editor. But when I change editor to "classic" again, perhaps to add another external link, my original HTML markup gets lost -- perhaps because the WYSIWYG-to-classic translator doesn't differentiate between WYSIWYG-created links and those marked up differently/manually. This makes the effort of adding HTML markup futile & frustrating. Can this be fixed?

Big problem. Break tags are not holding - on "save" the WYSIWG tool turns them into tags.
