Update @ 9:54am PST: I got to work about 30 minutes ago. After checking my email, I’ve been getting hammered from trackback spam. Trying to change file permissions to 000. *LoL*
I disabled trackbacks so I wouldn’t get spammed that way (you can read through the linked thread and the others off it for more information). There’s no fix or plugin right now, so this is all I could do for now.
Temporary workaround: In the root folder of WordPress, change the file permissions of wp-trackback to 700.
