Error logs are one of the fastest ways to understand why a website is failing. They can point to missing files, PHP errors, plugin problems, permission issues, and exhausted resources.
Start With the Time
Find the time the problem happened and look at log entries around that point. A log full of old warnings can distract you from the current error.
Look for Fatal Errors
Warnings and notices can matter, but fatal errors are the ones that usually break a request. In PHP logs, look for phrases such as Fatal error, Uncaught, or Allowed memory size exhausted.
Match URL to Error
If one page breaks and the rest of the site works, check logs while loading that specific URL. The relevant error often appears immediately.
Recent Changes Matter
Connect the log entry to what changed: plugin update, PHP version switch, file edit, migration, permission change, or new rewrite rule.
When opening a support ticket, include the URL, the approximate time, what changed recently, and any error text you can see. That makes troubleshooting much faster.
