Have you checked the Elgg wiki?
@Jan - Probable cause - most plugins come in zip format with two folders inside them, one outer folder and one inside that the real plugin folder....... that is the folder to be uploaded to the server if not you upload the whole you get the error message
"is a misconfigured plugin. It has been disabled. Please see the Elgg wiki for possible causes"
Hope this helps :)
