No, it's strange. I don't know much about adblock plus, but I know it's the problem. Here's what I did to prove it:
I loaded the Blogger :: Edit Layout page on the editing blogger page. (that's http://www2.blogger.com/rearrange?blogID=
[and my blog id here] )
I click on "edit" for one of the widgets, and it opens a popup window with url http://www2.blogger.com/rearrange?blogI ... editWidget
[...and so on]
I then edit the widget, and everything works, EXCEPT, when I click "Save" absolutely nothing happens, and, if the widget is a photo widget, the photo doesn't appear to upload.
Now, when I was there, with adblock enabled, I click the stop sign button and don't see anything listed in red
, so it would seem that it's not adblock's fault, because it's not blocking anything.
But when i disable adblock and go to the page again, it works like a charm.
So, no, I have no idea what the conflict is there, but for now I guess the whitelist works... You should look into it i guess, because you know more about adblock plus for sure.
