The old one left the "https" in the URL, and that no longer works in the DBpedia URL. This scriptlet fixes that:
drag this link to your bookmarks toolbar and rename it
or just take the following scriptlet code:
javascript:location.href=(location.href.replace(/https:\/\/en.wikipedia.org\/wiki/,"http:\/\/dbpedia.org\/page").replace("(","\%2\8").replace(")","\%2\9"))
