Pantheon gotchas

Troubleshooting

Pantheon uses Nginx instead of Apache. This is only relevant when dealing with code that normally would go in an .htaccess file.

Pantheon uses MariaDB instead of MySQL. Switching between the two should be seamless unless you’re writing raw queries.

⁠

Pantheon recommends using 3rd party services for mail⁠

. Password reset and other system emails won’t be delivered reliably otherwise.

You may see 504 Target Not Responding on the first visit to non-production environments in the morning.

This is usually because the container is idle⁠

and will go away on refresh.

Debugging

PHP debugging

Pantheon’s PHP logs logs/php-error.log only capture errors. No warnings, no notices.

Use syslog(LOG_ERROR, "My awesome message") in php code to log

To monitor you can use ssh and tail -f logs/php-error.log

These errors should also be logged to the Pantheon dashboard real time. (See “Errors” in the sidebar)

Reference

⁠

PHP syslog()

⁠

WP debugging

If this is set in wp-config.php then errors are also logged to wp-content/debug.log

define( 'WP_DEBUG', true );

define( 'WP_DEBUG_LOG', true );

Other WP debugging resources

Note there is no Terminus command to access logs

Updating Docker can bork Lando. If that happens, quit Docker and

reinstall Lando⁠
