This patch is not for 126.96.36.199p8, so don't apply it as it will break your server. The issue handled in this patch has been solved in 188.8.131.52p8 so no patch is required. I just tested the aps package list update here and it works fine in 184.108.40.206p8. Do you get any errors on the screen or in the ispconfig system log in the monitor? Thats possible as it may contain old package versions.
