Replace the actionStrings_it.properties within Lexmark\MarkVision Server\www\webapps\messenger\WEB-INF\lib\messenger.jar with the attached file. Please note:
You can use any compression tool that is capable of opening a JAR file to do this.
Be sure to overwrite the existing file with the attached one.
While overwriting the file, make sure the Save full path info optionis deselected. This ensures that the path information of the attached file as detached in the local machine is not carried over when it is inserted into the messenger.jar
Restart the MVP server and the web server.
Then invoke MVP Messenger. The problem should now be resolved.
