Why doesn't LabTutor Server display the latest version of a custom experiment?

If the latest Experiment Version is not displayed by LabTutor Server, then the Experiment Version Number was not updated properly in LabAuthor. 

In order to correct this problem: 
  • Open the experiment in LabAuthor
  • Go to Edit, Experiment Preferences and update the Version Number for the Experiment
  • Save the Experiment
  • Then Save a new Experiment Installer. 
  • Upload and Install the new Experiment Installer on the LabTutor Server
