Thread:Extension talk:CategoryTree/Permissions issue using version c7333ea on mediawiki 1.23/reply

Have narrowed it down to a read permission issue - whitelistread is not sufficient for this url:

index.php?skin=vector& uselang=en& debug=true& action=ajax& rs=efCategoryTreeAjaxWrapper& rsargs%5B%5D=Customer_Pages& rsargs%5B1%5D%5Bmode%5D=10& rsargs%5B1%5D%5Bhideprefix%5D=20& rsargs%5B1%5D%5Bshowcount%5D=true& rsargs%5B1%5D%5Bnamespaces%5D%5B%5D=12& rsargs%5B1%5D%5Bnamespaces%5D%5B%5D=14& rsargs%5B1%5D%5Bnamespaces%5D%5B%5D=100& rsargs%5B%5D=json

The user has read access to the three indicated namespaces, but without a title there appears to be no way to grant access to this url
