Recently active topics in PBwiki tagged with google gadgets

I have not been able to include any google gadgets recently. After pasting the code I press "review" but nothing happens.
I tried several different gadgets but no result.
I had installed some of these last year with no problem.

I inserted a google gadget into my 2.0 wiki page then saved, only to realize that I had made a typo in the script source...
when I went to edit the page and double clicked on the the gadget, the > and < symbols had all been encoded... when I made a change to the typo and hit finish and then saved, the plugin was all messed up.

Has anybody else seen this?
