WordPress Website Down Alert

Be the first to know when your website shows the dreaded WordPress White Screen of Death

Homepage monitoring and White Screen of Death alerts for WordPress

Know quickly when your WordPress website stops working properly. Don’t let a silent website failure cost you traffic, leads, sales, or trust.

WordPress Website Down Alert is a lightweight monitoring plugin that checks your homepage at regular intervals and alerts you if your site appears to be down, broken, missing key content, or showing signs commonly linked to the WordPress White Screen of Death (WSOD).

Rather than reacting to every small source-code change, it uses calmer health checks designed to spot meaningful problems while reducing false alarms caused by routine plugin updates, cache rebuilds, or harmless front-end changes.

Key Features

• homepage monitoring every 5, 15, 30, or 60 minutes
• instant email alerts to your WordPress admin email
• detects signs of website downtime, WSOD, fatal front-end errors, and broken homepage output
• optional expected homepage phrase monitoring
• recovery notifications when your site returns to normal
• built-in log of recent checks
• simple settings page inside WordPress
• manual check option
• reduced false positives after plugin, theme, or core updates

What It Looks For

This plugin is designed to detect practical warning signs, including:

• homepage unavailable or not loading
• very little visible content on the page
• missing title or body structure
• fatal error or critical error text
• disappearance of expected homepage content

Why It’s Useful

A website does not always fail dramatically. Sometimes it goes blank. Sometimes key content disappears. Sometimes it looks partly broken without you noticing straight away.

WordPress Website Down Alert helps warn you early, so you can investigate before the problem starts costing you visitors or revenue.

Quick Installation

• download the ZIP file
• in WordPress, go to Plugins → Add New → Upload Plugin
• upload the ZIP file
• click Install Now
• activate the plugin

Then go to Settings → Homepage WSOD Monitor to choose your preferred check frequency and set an expected homepage phrase.

Important Note

This plugin runs inside WordPress. If your entire installation is completely unable to run, no internal plugin can send alerts.

For best protection, use it alongside an external uptime monitor.

Optional Setup (Recommended)

Go to:
Settings → Website Down Alert

From here you can:

• choose how often your homepage is checked
• set an expected homepage phrase (recommended)
• adjust the minimum visible content threshold
• view logs of recent checks
• run a manual check at any time
• reset the baseline after updates or site changes

How Alerts Work

Emails are sent to your WordPress admin email address.

You’ll receive alerts if:

• your homepage cannot be loaded (website down)
• the page shows signs of a serious error or broken output
• visible content drops unexpectedly or key text disappears
• the site shows symptoms commonly linked to the WordPress White Screen of Death (WSOD)

To reduce unnecessary notifications, the plugin:

• waits for repeated issues before sending some alerts
• ignores short-term changes after plugin or theme updates

You’ll also receive a recovery email when the homepage returns to normal.

Important Note

This plugin runs inside WordPress. If your entire site is completely down and WordPress cannot run at all, no internal plugin can send alerts.

👉 For maximum protection, it’s sensible to pair this with an external uptime monitor.

Who This Is For

• website owners who rely on uptime for income
• WordPress developers managing client sites
• eCommerce stores (including WooCommerce)
• affiliate and lead generation websites
• anyone who wants an extra layer of reassurance

Protect Your Website. Protect Your Income.

A broken or unavailable homepage can go unnoticed — costing you traffic, enquiries, and sales.

WordPress Website Down Alert helps you spot problems early, including downtime, missing content, and issues such as the WordPress White Screen of Death, so you can act before they escalate.

What to Do Next After a Website Down Alert or WSOD

If you receive a website down alert or a WordPress White Screen of Death (WSOD) warning, the first step is always to clear every layer of cache.

Clear:

• your WordPress caching plugin
• any server-level cache
• your CDN cache (if used)
• your browser cache

A cached broken page can sometimes continue to display even after the underlying issue is fixed. Clearing cache often restores the site immediately — but you should still investigate the root cause.

Step 1: Clear all caches

After clearing all caches, reload your homepage in a private/incognito window.

If the site returns, that is a good sign — but continue with the checks below.

Step 2: Identify what changed

Think about what happened just before the alert:

• plugin updates
• WordPress core updates
• PHP version changes
• new plugin or theme installation
• code edits (functions.php, templates, etc.)

Most website-down events or WSOD issues are triggered by:

• plugin conflicts
• theme conflicts
• PHP errors
• memory limits
• server configuration changes

Step 3: Disable plugins

If you can access wp-admin:

• deactivate all plugins
• reactivate them one by one until the issue returns

If you cannot access wp-admin:

• connect via FTP or file manager
• rename:
  wp-content/plugins
  to something like:
  wp-content/plugins_old

This disables all plugins at once. If the site comes back, a plugin is the cause.

Step 4: Check your theme

Switch to a default WordPress theme (such as a recent Twenty Twenty-* theme).

A broken or incompatible theme can also cause a website down state or WSOD.

Step 5: Check your PHP version

PHP mismatches are a very common cause of both downtime and WSOD errors.

• confirm your current PHP version
• ensure it is compatible with your theme and plugins
• WordPress generally recommends PHP 8.3+

If the issue started after a PHP change, temporarily revert to the previous version.

Step 6: Check error logs

Look at:

• your hosting control panel error logs
• WordPress debug log (if enabled)
• WordPress fatal error emails
• plugin-specific logs

These often point directly to the cause.

Step 7: Check memory limits and server resources

Some downtime or WSOD events are caused by memory exhaustion or server limits.

If you see memory-related errors:

• review PHP memory limits
• check recent traffic spikes or heavy processes
• speak to your hosting provider if needed

Step 8: Roll back the last change

If the issue started immediately after an update or edit, roll back that change first.

This is often the fastest way to restore your site.

Step 9: Reset your baseline (after fixing)

Once your site is stable again:

• go to Settings → Website Down Alert
• reset the baseline

This ensures future alerts are based on the corrected version of your homepage.

Step 10: Keep monitoring

A site that goes down once can go down again.

Your plugin tells you something is wrong — but the real fix comes from identifying and resolving the cause.

Common Causes of Website Down Alerts / WSOD

In most cases, the root cause will be one of:

• plugin conflicts
• theme conflicts
• PHP version mismatch
• fatal PHP errors
• memory exhaustion
• recent code changes
• caching layers serving broken output
