We use moodle version 2.2.1 and an inbuilt theme called "Afterburner".
We would like to limit the number of courses on the front page to 20. But as of now 43 courses are being displayed on the front page under "Available Courses". We did research online but the solution is to upgrade to Moodle Version 2.5. However we do not want to upgrade due to the fear of the database being messed up. The site is live lots of students learning online. We also tried to go to front page settings and limit the number of courses per page to 20 but still it does not work. You can take a look at our website in the attached file.
