Thread:Project:Support desk/Wrong classification in Category pages (classified as " ")/reply

If you have a link to your wiki, that would be helpful. On the page ClienteWebService do you have something like or other formatting characters in the part after the pipe (|) of the category link?

The output of http:///w/api.php?action=query&list=categorymembers&cmtitle=Category:BVP&cmprop=ids|title|sortkey|sortkeyprefix would be helpful
