Issue with "Add to Wishlist" button (CLOSED)

There is an issues with "Add to Wishlist" button, it is not working.
After a deeper investigation it looks like the onclick function has a "de" prefixing the item id, please see the screenshots.
I managed to add the item to the wishlist by calling the function removing the "de" from the argument and just leaving the string representing the id.
Please see the screenshots.

It appears that this has not been fixed yet.
I have been unable to register on WishList for about 4-5 days now.

Interesting. I can duplicate the problem but don't know what's causing it. 
I have opened a bug report. Thank you for bringing this to our attention. 

Here's a work around ......

Add it to your cart and then when viewing your cart, you can move it to your wishlist

Sorry that this bug hasn't been squashed yet. 
In the meantime, if you haven't yet added an item to a collection, you can add it to your wishlist that way.
I apologize for the inconvenience while we're waiting for this to get fixed.

Just following up on this. The problem has been fixed. 
Thank you for the report.
