unable to add or delete passwords

Hello!

After upgrading to 1.4, it seems that all the passwords that are entered cannot be modified, deleted, or new ones can’t be added. Once you make the edits to the multiple passwords page, you hit “ok” and then apply the changes, the passwords revert to how they were before.

A client is really needing this to work again, I really hope you can help.

Thanks!
