Same problem here:
I have a website where i was able to add a lot of picasa albums some time ago (it was already G+). Those albums are still viewable correctly now, but when I want to add some new albums, I receive the error message using picasa import button. I didn't change any of the settings!
I tried to upgrade to the latest version (3.2.2), but it didn't resolve the problem
Any idea when you can fix this problem or is there a way to find out what the exact problem is?
Thanks in advance.
