Magazine Layout Problem (some sites only show 5 posts)

Hi There

I love your template and have used it on several sites already. I do however have a problem with the Magazine Layout option. On one web site I can get it to display 8 posts on the front page but on all other sites it will only show 5 max. I have played around with settings and cross-checked settings between the one that can display 8 posts and the one’s that don’t but I simply cannot find any differences.

Here’s two sites to compare:
http://free-energy.co.za/ (shows only 5 posts)
http://magaliesburg.org.za/ (shows 8 posts)

Please can you help on this? I am surely missing a setting somewhere.

Keep up the great work, I will soon donate and get premium support and link removal, one of the best templates for wordpress I have ever worked with.
