Hello,
I just upgraded to version 2.0-M1 from 1.2.17 on Windows 7 64bit and when I try to log into the web interface I get Server uses incompatible version of communication protocol.  I stopped the services and ran the installer with the /SILENT option and everything seemed to go fine.  The services started back up but I get that error when trying to connect using a web browser.
Any ideas and assistance would be greatly appreciated.  I've been using this for a couple weeks now and really like it so far.
Thanks,
Damon
			
			
			
				I have the same problem using 2.0-M1 WAR file on Linux, so I guess the webui wasn't updated to 2.0 protocol with the rest of the code?
			
			
			
				That's weird, you can try to undeploy, stop servlet container, remove working/temp directory and start deploy war file again.
			
			
			
				Seems I needed to run the 2.0 web installer.  Once I did that, it's all working as expected.
