I used http://site-perf.com/ to test the speed of my site (http://sweatingthebigstuff.com) and it shows one file that gives a 404 error. That file does not exist (hence the error), but how do I found out how to fix it? I don't know where it is being called (definitely not in the code).
The file in question is:
sweatingthebigstuff.com/wp-content/themes/WillTech_5_3_2010/lib/images/icon-rss.gif
I assume that I used to have a file but since deleted it. It was in a widget and it is now pointing to a png file.
Any ideas?
