After an upgrade, you notice that pages are "mixed up" - that is, not all pages show the new version on their title bar. This may lead to many different errors and malfunctions.

This may be caused by two things:

• You have the page in the clients cache. Clean up the browser cache and retry.
• The Tomcat system caches are not updated. Do this to clean them up:

/etc/init.d/queuemetrics stop
rm -rf /usr/local/queuemetrics/tomcat/work/Catalina/*
/etc/init.d/queuemetrics start

This should fix all issues.
