[Feedback] doesn't save

[vendethiel]

When I try and save some, it says "feedback added", but the list stays empty

I might be missing something, as I don't know how it works...

It kind of destroys the public profile page too. I installed it once to see what it does exactly and I went to view my profile and it was gone. All white.... I believe. It's been a month or better since.
