I have a website receiving unusually high number of Error 404 results, targeting non-existent /logo.png file. It is requested at root (
www.example.com/logo.png) while it's real location is elsewhere. I noticed those errors in Analytics by looking at Site content/All pages with Page title as primary dimension.
I noticed this in Google Analytics, but couldn't find anything useful in Full referrer/Referral path secondary dimension (it is showing it as (not set)).
Everything I could mine is that it exclusively appears on Firefox/Desktop.
Website is made in WordPress.
Is there any idea what can be the cause for such behavior?
