The KDE Frameworks book was imported into the English WikiToLearn twice, once under the name [[http://en.wikitolearn.org/index.php?title=/KDE_Frameworks | /KDE_Frameworks]] and again under [[http://en.wikitolearn.org/index.php?title=KDE_Frameworks | KDE_Frameworks]]. The slash-prefixed pages need to be deleted.
A full list of pages to delete can be found at http://en.wikitolearn.org/index.php?title=Special%3AAllPages&from=%2F&to=A&namespace=0
