I made a post called "Odd Error Log" and there is just a blank page.
Anyway, I *did* have a very odd error log show up tonight that seemed to show that my database was being updated - or trying to be. It seemed to be targeting the Pro-Sites plugin.
I had a look at my visitor logs and the IP that was doing it was from Turkey.
I've attached the file instead of trying to include it in the post this time. I'm not sure if this is an attempt at an exploit or not, but I thought it was very much worth mentioning.
