Troubleshooting steps
Browser issues
Check if it is not due to a conflict with a browser add-on by editing in incognito mode with your browser.
PHP issues
- If you’re using PHP 7.3 or earlier, upgrade your PHP version to PHP 7.4.
Note
From Elementor version 3.19, PHP 7.4 will be required. For more details about Elementor system requirements, see System Requirements.
- If you’re using PHP 8.0 or later, revert to PHP 7.4. Later versions of PHP may have compatibility issues with Elementor.
Hosting issues
- Ask your hosting provider to increase the timeout value of your server.
- Ask your hosting provider to check the database encoding of your website.
Plugin Issues
- Deactivate all your website plugins except Elementor and Elementor Pro. If your site works, one of these plugins is probably causing the error. To learn more about activating and deactivating plugins see, Activate and Deactivate plugins.
To isolate the problematic plugin, reactivate the plugins one at a time, until one of them breaks the site.
