Looks like your plugin is incompatible with your WP version. Check the plugin homepage or the plugin database here and see if you need to update the plugin or WP itself. If you can’t, disable it like krembo99 suggested or roll back your WP installation to a version that does work with the plugin if you desperately require the plugin to work.

Try disabling
<div id="incominglinks"></div>
on line 33 in /wp-admin/index.php by changing it to
<!-- <div id="incominglinks"></div> -->

I don’t know if it works though, as I’m running WP 2.5.1 on my site. If you get an error or it fails to work in some other way, just change the line back to the original version.

Try disabling your last post (change the publication status) and see if that fixes the layout. If that is the case, something you put in your post is probably messing up the layout, so try removing segments of the post to identify the culprit.

You’re welcome.

I should add that my problem with accessing the widgets administration page was caused by an empty widgets.php in /wp-admin/ and unrelated to the wp-cron problem. Again, uploading the file (widgets.php) resolved the problem.

I recieved the same warning. Disabling all my plugins did not help anything and I could also not access the widgets administration page.

I took a look at cron.php file in /wp-includes/ and found it to be empty! A quick upload of the cron.php file fixed everything.

In other words, check if there was an FTP error when you uploaded the cron.php file to /wp-includes/.
