My web logs show a repeating error when users access my site. I get the message, "18.104.22.168 tried to load www.garydarling.net/photos/libraries/themes/dark/". The IP address changes obviously, but I'm having trouble tracing the source.
My thinking is there is a script buried somewhere in the code, probably in the /libraries subfolder, that is making a call to the /themes folder without providing the ROOT variable or a"../" first. When a user clicks something in the site that calls this script, I get an error log entry. I have no idea what the user sees at that point, but I'm assuming it's transparent to them as the theme is already loaded. In fact, I can cause the error message from my own IP address, and I see no hiccups.
Any ideas what is doing this?
