Searching for "red ribbons (character)" works normally, but clicking on the tag gives an error message stating "You can't access that page"

I assumed it was because clicking on the tag tries to send you to https://ponerpics.org/tags/red+ribbons+(character), instead of replacing ( and ) with %28 and %29 like in every other url, but the url still doesn't work when replacing them manually.
