When that frustrating 404 error pops up, I start by refreshing the page, then check if the site is down for everyone using a tool like Down For Everyone Or Just Me. If that's clear, I clear my browser cache and cookies, then try a different browser or incognito mode. For persistent issues, I look at recent changes to plugins or themes, and in extreme cases, check server error logs or disable security plugins temporarily to isolate the problem.
