There have been discussions about the problems in their Forums sections about the upgrade and problems. Their upgrade basically eliminated users who are functioning with older versions of browsers. Photobucket is particularly fussy with Safari users since the upgrade. If you have the very most recent version of most any of the browsers you will be fine. I had always used Safari and now it will crash if I try to use the Photobucket website. Here at work we have older browser versions. We are basically locked out of our hard drives by the IT person so we can't change things. I did manage to get around it though and downloaded the latest version of Firefox and it seems to work fine.
So, if you are experiencing problems with Photobucket, update your web browser to the latest version.
