Open Source Document Management System | OpenKM

I am using openkm 5.1.7 But the forum functionality is not working.This quetion is for the second time I was trying to implement the extension but i cannot create my own extension.Please help me. I need the source code of this forum or please add it in the next version of openkm.

openkm has extensions?! where'd you get it form? are there more extensions?

Most of the extensions are not included in OpenKM Community, but all them are in OpenKM Professional. In short: if you want any of these extensions you need to pay.

i did not know there was a openkm professional! can i get more info on it? price, features etc?

Please, fill the form at http://www.openkm.com/en/buy-now/price-request.html.
