If you are unable to see the navigation buttons within a module, this is most likely due to the display resolution on your computer. When the screen is zoomed in too far, certain interface elements can fall outside the visible area, which prevents the navigation buttons from appearing.
To resolve this, hold down the Ctrl key on your keyboard and scroll your mouse wheel downwards. This will zoom out the page and increase the visible area on your screen. Once the zoom level has been reduced, the navigation buttons should reappear and become accessible again.
For Apple users: Hold down the Cmd key while scrolling to adjust the zoom level.
If you are using a laptop trackpad instead of a mouse, you can achieve the same result by holding down the Ctrl key and swiping down with two fingers on the trackpad. You may need to adjust the zoom a few times until the full module interface is visible.
If you continue to experience issues after adjusting the zoom level, try the following quick checks:
Ensure your browser window is maximised.
Verify that your browser is set to 100 percent zoom or lower.
Try an alternative browser to rule out a display-specific issue.
Refresh the module page once you have adjusted your settings.
These steps usually restore the full module view and make all navigation controls visible again.
