What do I do when the next button goes to the wrong page?
Are the Next and Back buttons taking you to the incorrect pages in your course? For example, If you're on Page 1, clicking Next will take you to Page 4 instead of Page 2.
First, it is important to note that the order for the Next and Back buttons follows the arrangement of module sets you have set up in Course Setup > Content.
It does not follow the arrangement you've set up in Course Setup > Appearance.
If changing the order in Course Setup > Content doesn't resolve the issue, you can also try the steps below.
Go to Course setup > Content
Drag one of the pages, modules, or module sets (depending on your particular issue) into a different position
Drag the page (or other) back into its original position.
This method should reset the cache and make the ordering work correctly.
