When your website throws an error, the temptation is to start guessing. Don’t — the error log almost always tells you exactly what went wrong, in which file, on which line. Learning to read it turns troubleshooting from guesswork into detective work. Here’s how.
The cPanel Errors tool
The quickest way to see recent errors is the Errors tool under the Metrics section in cPanel. It shows the most recent entries from your site’s error log in a readable list. Each entry includes a timestamp, the type of error, and usually the file and line involved. When something breaks, this is the first place to look.
Finding the raw error_log file
For a fuller picture, your site keeps a file called error_log in the folder where the error occurred — often in public_html or a specific subfolder. Open File Manager (with hidden files shown) and look for it. The newest entries are at the bottom.
Making sense of an entry
A typical PHP error line names the problem and its location, for example a fatal error that mentions a specific plugin’s folder and a line number. That tells you precisely where to look. Errors come in a few flavours:
- Fatal errors stop the script and usually cause the visible problem (a 500 error or white screen).
- Warnings don’t stop the site but signal something isn’t right.
- Notices are minor, though a flood of them can hint at deeper issues.
Using the log to fix problems
Say your site shows a 500 error. Check the log, and you might see a fatal error pointing to a specific plugin file. That immediately tells you which plugin to disable. Without the log you’d be disabling things at random; with it, you go straight to the cause. This is why we always start with the log.
The web server logs
Beyond PHP errors, the server keeps access logs (every request to your site) and its own error logs. Access logs are useful for spotting attacks or unusual traffic — a flood of requests to wp-login.php, for instance, signals a brute-force attempt. You can view raw access logs under the Metrics section.
When the log points beyond your site
Some errors are server-level rather than something in your files. If the log shows an error you can’t place, or points to a server configuration issue, copy the exact line into a support ticket. That single line usually tells us precisely what to fix — it’s the most useful thing you can send us.
Reading logs is a skill that makes you far more self-sufficient. Start with the Errors tool, learn to spot the fatal errors, and most problems reveal their cause quickly.
