Overview
If your WordPress site crashes or shows a critical error immediately after activating the Search Atlas plugin, the most likely cause is a PHP version incompatibility. Running the plugin on an unsupported PHP version can cause a fatal error and may take your site offline.
This article walks you through confirming the root cause, recovering your site, and safely re-activating the plugin once your environment meets the requirement.
Root Cause
The Search Atlas WordPress plugin requires a minimum PHP version to function correctly. If your hosting environment runs an older PHP version than required, WordPress will throw a fatal error when the plugin initialises, making your site inaccessible through the browser.
Step 1 — Check Your Current PHP Version
Before making any changes, confirm which PHP version your server is running. The exact steps depend on your hosting provider. Common options include:
- Hosting control panel (e.g., cPanel, Plesk): Look for a PHP or software configuration section within your control panel. Your hosting provider's documentation will show you exactly where this is located.
- Managed WordPress hosting dashboards (e.g., Kinsta, WP Engine, SiteGround): Check your site's settings or environment section. Refer to your host's support documentation for the exact location.
- No panel access: Contact your hosting provider directly and ask them to confirm the PHP version your site is running.
If your PHP version does not meet the plugin's minimum requirement, that is the cause of the crash. Proceed to Step 2.
Step 2 — Recover Your Site (If It Is Currently Down)
Because the WordPress admin dashboard may be inaccessible when a fatal error is active, you may need to deactivate the plugin directly on the server. You can do this using FTP, SFTP, or your hosting provider's file manager tool.
- Connect to your server using an FTP/SFTP client or open the file manager available in your hosting control panel.
- Navigate to your WordPress plugins directory (typically found within the wp-content/plugins/ folder).
- Locate the Search Atlas plugin folder.
- Rename or remove the folder so that WordPress can no longer load the plugin. WordPress will automatically deactivate a plugin when its folder is no longer accessible.
- Reload your website in a browser. Your site should now be accessible again.
Once your site is back online, log in to your WordPress admin dashboard to confirm the plugin is shown as inactive.
Step 3 — Upgrade Your PHP Version
Contact your hosting provider and request that they upgrade your PHP version to one that meets the Search Atlas plugin's minimum requirement. Most managed hosting providers can do this quickly, and many allow you to change the PHP version yourself through their contro
