Read my previous post.

It sounds like you have the wrong host for your website. Unless you have an extremely large volume of content (video/images) you should not be even close to being out of space. You need to check your type of hosting account or find another host (listed on the front of this website) for one that offers sufficient disk space.

Would help greatly if we had links to those websites. ANd is this a self-hosted wordpress or on wordpress.com?

Not sure we understand your problem. Out of disk space? or something else? Do you have a cache plugin enabled? And if so which one?
We need more and cleared info. Plus version of WP.

What is wrong with the date of the email?

First disable your cache. Then You only have to disabled the plugins for a minute or two. Not sure how you are monitoring CPU though. If using top you will know right away. Some host interfaces are delayed.
Also be sure to try the twentyten theme in case the issue is related to the theme.

Should be specified in your theme’s header.php.
Would need to know what it has.

Its a Paypal issue not WP.

Would open a ticket with your host’s support. Sometimes their install scripts especially when you made changes like you described may have caused the issue.

Try clicking on the icon to edit full screen.

Would contact your host before presuming anything. Have seen where a server crashed and the host restored their backup without informing their clients. So everything would appear to have been rolled back.

Its held in a cookie so is computer based. Should be in wp-pass.php
You can change the time the cookie is valid for. Other than that you would need to see if you could somehow delete the cookie.

First try going to the Twentyten theme to see if that resolves it. Sometimes things work differently even though they seem idenbtical.

Easiest probably for you to just write a shell script (if Linux/UNIX) or batch file if windows to copy whichever image you want to the destination file. Then run as a cron job at appropriate times.

day.sh

#!/bin/sh
# This copies image for daytime
cp /mydir/dayimage.png /wp-content/uploads/background.png

night.sh

#!/bin/sh
# This copies image for nighttime
cp /mydir/mightimage.png /wp-content/uploads/background.png
