Speed – how to solve my header 404 issue?

What you are showing, is that the image monychhim.com/wp-content/themes/foodiepro/images/header.png doesn’t exist.

One thing to check out is to see if any of your plugins are causing you site to load slow, using the plugin P3 (Plugin Performance Profiler).

Thanks and sorry for the late reply! I’ve installed the plug-in you’re referring to and I’ll use it to clean up my site.
