“The site is experiencing technical difficulties. Please check your site admin email inbox for instructions”

By 25th November 2019 November 28th, 2019 No Comments

WordPress 5.3 introduced a great feature: when an update causes an issue, it enters a special recovery mode and sends you an email. That’s great, unless……

You don’t get the email – then what do you do?

Your site is now offline displaying “The site is experiencing technical difficulties. Please check your site admin email inbox for instructions”.  You should have received an email similar to that below:

Howdy!

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins or theme, plugin name or theme.

First, visit your website (https://yourwebsite.com) and check for any visible issues. Next, visit the page where the error was caught (https://youwebsite.com/url and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can’t access your dashboard normally, WordPress now has a special “recovery mode”. This lets you safely login to your dashboard and investigate further.

Special one-off login for your site

To keep your site safe, this link will expire in 1 day. Don’t worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

Error Details
=============
Specific details of the error

The email is really helpful:

  1. It provides a link so you can still access the backend
  2. Details what has caused the issue

This would be really helpful and will give you all the details to identify the plugin or theme that is causing the issue and making it super easy to fix.  But, what can you do if the email does not get delivered or goes to an old email address?

If you can, login to your control panel and look for the error_log file, this should detail the error.  You might need to turn on debug mode in WordPress, so it captures all the details:

Turn on debug mode

By default, the debug mode in WordPress is turned off.  As we want to try and find the cause of an issue, we want to turn this on so as much information as possible is captured in the error logs.

To turn on debug mode you need to open the wp-config.php file and change:


define( 'WP_DEBUG', false );

to


define( 'WP_DEBUG', true);

Check your PHP Version

We also recommend that your check your PHP version, WordPress now recommends your site uses PHP7.3 or higher.  You can check your version of PHP by creating a file e.g. info.php with the following code:

<?php
   phpinfo(); //PHP function to get php information

To view the version of PHP simply visit https://yoururl.com/info.php.  If the version of PHP is less than version 7.0 you should try upgrading the version via your control panel.  Most hosting providers allow you to choose the version of PHP.  If not, you may need to contact you hosting provide to update the version for you.
