Search Engines Not Working?

Today I clicked on Mozilla Firefox. Out of the blue the screen was completely blank except the top part with the address bar. So, I tried Google Chrome and Internet Explorer. They both have the exact same issue as I described with FireFox, except Chrome and IE say the page can't be displayed. Another thing I noticed is that now Chrome and IE open up 3 pages whenever I click just once. Troubleshooting couldn't identify the problem and my AVG AntiVirus program couldn't detect a single threat from a whole system scan. I know it's not an internet issue because I could still play Minecraft on a server. I've tried everything (examples- safe mode, clearing cache/history, rebooting) I can't uninstall and reinstall the programs because it keeps saying page can't be displayed! I have no idea what the problem is if anyone knows please help. Also does anyone know a Tech support number I can call?

Minecraft world save problem. Need some

I'm a moderator on a Pixelmon server. We had originally had the 2 servers on 1 server, but the owner switched it so now we're paying monthly for 2 dedicated servers. When the switch happened the owner transferred server 1 over and there lag spikes started happening every 5-7 minutes. Now they are world saves.

We can't figure out how to fix it. The world save was on a autosave schedule for every 30min but when we switched hosts it bugged out. Now its every 6 minutes and nobody can figure out how to change it.

I don't have access to the console so I can't see how its set up but the owner has tried everything he can do as well as the admin. The owner thinks its because of the new host which makes sense because thats when we came across the problem.

There were some corrupted chunks that were removed. There might be more but we haven't found any. There's a map limit so there's only so many chunks and i've been around it all.

Any suggestions? Sorry if this is a little confusing.

Added (1). We have restarted the server a lot as this has been going on for about 2 weeks or more. The server provider can't figure it out that I know of but I guess hes been busy. Any other ideas?

And why did I fail to bind to port?

How to keep a player from using commands on a minecraft bukkit server?

I have a small private bukkit server for me and my friends, but one of my friends keeps messing with the others. Instead of banning them, we want to troll them my setting their spawn in the nether. How do you keep a player from using commands such as /spawn or /sethome or /home?
