Page load slow - call for bad image file
I recently turned on ads for my site and the page load time immediately took a hit. GTMetrix told me I am getting a call for a bad image file, which is causing up to 8 seconds extra load time. I was able to find where the image call was coming from by performing a search on PHPMyAdmin. The image is a stock theme image that was a placeholder for the header ad space. I have since disabled the header ad to speed up site, but gtmetrix is still telling me I am getting a call for that image, which doesn't exist in my media library or files. I have attached a link to the gtmetrix error. Any help is appreciated.
