 * I have received this alert from WP about this version on similar sites:
 *     ```wp-block-code
       WordPress has 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, Search Exclude.First, visit your website (https://thefintrytrust.org.uk/) and check for any visible issues. Next, visit the page where the error was caught (https://thefintrytrust.org.uk/wp-admin/post.php) 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.https://thefintrytrust.org.uk/wp-login.php?action=enter_recovery_mode&rm_token=H9A1b84eK4tYPq9VDdrGVz&rm_key=HNTuPTZIg5wwrAFtFucwTqTo 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.When seeking help with this issue, you may be asked for some of the following information:WordPress version 6.7.1Active theme: Divi (version 4.27.3)Current plugin: Search Exclude (version 2.1.9)PHP version 8.2.26Error Details=============An error of type E_ERROR was caused in line 180 of the file /home/customer/www/thefintrytrust.org.uk/public_html/wp-content/plugins/search-exclude/lib/controllers/class-backend.php.
