      Background:
      Was running Core 2.03 and Modbus I/P (both unlicensed). Had five Modbus I/P data sources setup with less than 20 registers each. Worked fine.
      Decided to upgrade to Core 2.1 and associated modules as I want to move to licensed versions.
      Had problems upgrading, so uninstalled 2.03 and installed 2.1 then setup one Modbus I/P data source with five registers. Works fine.

      Problem:
      Tried to add a second Modbus I/P data source, but when trying to save the Modbus IP Properties, get the following error:
      com.serotonin.m2m2.http.vo.HttpReceiverDataSourceVO cannot be cast to com.serotonin.m2m2.modbus.vo.ModbusIpDataSourceVO

      I have restarted the instance a few times.
      I removed the HTTP data source and restarted the instance, then tried again to add a second Modbus I/P ds, but now get "A server error has occured".

      Any help is appreciated.
      Thanks.

        Hi Glen,

        Did you clear your browsers cache? Here are the upgrade instructions in case you missed them: http://infiniteautomation.com/index.php/download/2-uncategorised/98-upgrade-instructions

          Hi Joel,

          I switched browsers from IE to Firefox, but no help (of course MS updates installed IE11..).

          I did find the problem...
          JRE1.6 was installed, and the partially allowed Mango to function.
          I installed JRE1.7 (client version) and had no functionality at all...
          So I installed the server version of JRE1.7 and now seem to have everything I need immediately working fine.

          Thanks for your quick response.
          Glen

            That is interesting. Also make sure you have JDK 1.6 or 1.7 installed and you may need to set a JAVA_HOME environmental variable pointing to the JDK installation.

            Joel.

              Joel, yes I did have to set JAVA_HOME as well.

              Quick side question - where can I change the Mango web server port from 8080 to another port ... 9999 for eample?

                It's in the /classes/env.properties file.

                Joel.
