Should consider upgrate to nighly build ( http://integration.openkm.com -> here the migration from 6.3 to 6.3.1 http://wiki.openkm.com/index.php/Migrat ... 3_to_6.3.1 ) because we have done a lot of changes moving from quirks mode to doctype compliance ( now application supports better all browsers, specially IE, always the most problematic browser ).
Download the OpenKM.war file from integration.openkm.com ( http://integration.openkm.com/6.3/ here you have the download link ) and then follow the steps described on migration from 6.3.0 to 6.3.1
