well, I already had php5 and mySQL 5 installed and other modules installed and they were working fine and I had no problems with my home page. up till the point where I installed extCal, that's when I started getting a blank page as my home page. So that would probably mean that extCal isn't compatible with php5 and mySQL 5. sounds logical to me actually even though I'm not the smartest person in the world.
