I searched and didn't find any related information on this. Maybe someone can have some suggestions.
I am using WP 2.1.2 hosted with a company I've used for years. This past weekend, a friend notified me that my links page (http://ceffyl.net/wordpress/links/) was full of links for Cialis and other spam.
I used to have problems with comment spam, but have not had trouble with that for quite some time thanks to Spam Karma.
I have tried updating to 2.2, but ended up reverting to 2.1.2 because of errors I was unable to resolve. I may try upgrading to 2.3, if this would help the problem. However, some of the plugins I use (Extended Live Archive and others) are not compatible, so I would rather wait.
I'm using the latest Misty Look theme by Sadish, in case that helps.
What I have tried:
* I went through my site and found two files with persmissions set higher than 644 (excluding folders): xmlprc.php and a file for Aniga gallery. I modified the persmission to be 644 instead of 755 (not sure if this was the correct thing to do).
* Setting the spam settings on Spam Karma to the highest levels.
* Removing any bogus user accounts.
* Changing all user passwords.
Any suggestions would be greatly appreciated. This has me concerned.
