this sucksss

this is totally getting into my nerves. I'm tired of this.. it's like I've been editing and layouting my page for almost 3 days now and what???.... everything was in place and before I knew it the next time i log on it was totally un-aligned and ruined... now I give up.. I don't know what seems to be the problem, my script was running perfectly before I leave last night and now when i log on.. the same problem again..... =(
