I already had the main menu block on "no cache lifetime". My problem(s) has nothing to do with caches and updating the system module. Whenever I use that code,update the system module, clear the caches,etc...the code is displayed instead of the menu. Its so weird....Do you have any idea why the code is displayed instead of the main menu?
edit:::I fixed the problem!

I had doubled spaced between a few lines of code, but know it works.
