I've been trying since this morning and every time I try to add an item to my wl I get an error message. I have been trying to add by clicking the link on the picture from the account search page. I have tried both opera and chrome browsers on my Android tablet using the desktop site layout. I also tried clearing cookies and cache but it didn't work.
There is a new limit (500) to the number of items that you can have on your default wishlist. You can create a new category and make that your default and it will allow you to add again. Or you can clear out your default list and it will allow you again.
This is not a bug but a limit added so that people could move things from their unsorted list. You can still add things manually after 500. You just can't use the + wishlist function.
