Since changing over to XF, I have this fear of installing any addons/styles as I have had many issues with rebuilding cache data once the modification is installed. Basically it stalls quite often, leaving me with a blank page for the main site. Right now it's happened again, so I'm trying the Master Rebuild for the first time by using /install/.
But I'd like to know why this is such an issue, every time I make a modification I feel like I have to back my whole site up every time in case something goes wrong?
Update: Now it seems to be stalling over the Master Rebuild even. I'm really burning over this at the moment.
