This is the first time I've tried to sort it that way in awhile. That's one of the most useful ways for me to sort when organizing because I tend to add things in related chunks to each other.

It's the only one that's not working out of all the "sort by" options. Is it like this for everyone? Is it going to be fixed or has it been removed..?

Yep I get an error too. I reported this a while back and no one responded at all. Really annoyed about that

For the record: I have had this problem for months, too.

Moving and removing works for me. Sorting by item ID, official price and user price does as well, but I still can't sort by time line. When I click on timeline, the site reloads immediately, but the wishlist is completely empty, like this:

I have this problem too--no error message, but it just displays blank, for all of my categories.
