[jira] [Commented] (GUACAMOLE-1027) Guacamole logs “Wrong number of arguments”

["Nick Couchman (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GUACAMOLE-1027?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17084019#comment-17084019 ] 

Nick Couchman commented on GUACAMOLE-1027:
------------------------------------------

The most likely explanation for this is that you are using a mismatched version of Guacamole Client with Guacamole Server (e.g. guacamole-server 1.0.0 with guacamole-client 1.1.0).  Prior to version 1.1.0 the versions needed to match up.  Starting with version 1.1.0 there is some negotiation done between the two to better enable cross-version compatibility, thought it's still a good idea to keep them in sync.

If you have further questions please post to the mailing list before opening a JIRA issue:
