If this is the first time you set up uoCal on your Drupal site, you will have to run the uoCal cron job first. To do so:
- Navigate to Configuration.
- Under SYSTEM, click on Cron.
- You will be presented with a page listing all the cron jobs. Find the one called "uoCal Import Configuration". At the right of it, click on "Run".
Note: You only need to do this step once. Events will be automatically imported every few hours from uoCal.
