WordPress sends this email when a plugin or theme crashes part of your site. Your content is almost always safe. Here's what it means and what to do first.
What it means
This automated email means WordPress caught a fatal error - usually a plugin or theme calling something that doesn't exist after an update. The site may still be partially up; the email is WordPress telling you something broke in the background.
Why it happens
It's triggered by PHP fatal errors in plugins/themes. If you're getting these regularly, something is repeatedly crashing - often a poorly-maintained plugin.
A real example
A restaurant owner got WordPress's "Your site is experiencing a technical issue" email at 6am, two days after their host auto-updated PHP. The site had actually recovered on its own via WordPress recovery mode - but the owner did not know that, and spent the morning assuming the whole site was gone. This email means WordPress caught a fatal error and protected the front end; it does not always mean the site stayed down. Checking the recovery link in the email - or simply loading the site - usually tells you within seconds whether it is still broken.
What to do
- Open the email - it names the file and plugin/theme responsible.
- Check if the site actually looks broken, or if it's a background error only.
- Update or replace the named plugin/theme.
- If errors continue after updating, the plugin is likely abandoned - find an alternative.
Still stuck? If the emails name a plugin you can't identify or the site is misbehaving, we can trace the error and fix it properly.
