Check the Publish Queue
The publish queue is shared by everyone who uses the CMS. Once you submit a job to be published, it is wise to find your place in the line of jobs waiting to be published. Depending on traffic, it may take longer than you expect to see the published changes you make to your website.
To check the publish queue, go to the System Menu > Publisher > Active Jobs. You will be able to watch the progress of all the jobs that are spooling through the publish queue.
