Error logs record problems encountered by your website, including PHP errors, application crashes, and server-level issues. Checking them is usually the fastest way to diagnose a broken page or failed script.
Accessing Error Logs in Plesk
Go to Websites & Domains
Log in to Plesk and click Websites & Domains in the left sidebar.
Open Logs
Find your domain and click Logs.
Select the Log Type
Use the dropdown to switch between log types:
- Error log — PHP and web server errors for your domain
- Access log — all HTTP requests made to your site
Review the Entries
The most recent entries appear at the bottom. Look for lines marked [error] or PHP Fatal error for issues affecting your site.
Enabling PHP Error Logging
If your error log is empty but your site is broken, PHP error logging may be disabled. To enable it:
Go to PHP Settings
In Websites & Domains, find your domain and click PHP Settings.
Enable Error Logging
Set log_errors to On and ensure error_log points to a writable path. Leave the default path unless you have a specific reason to change it.
Save
Click OK and reproduce the error on your site. Check the log again.
For WordPress sites, errors may also be logged to wp-content/debug.log if WP_DEBUG_LOG is enabled in wp-config.php.
