I found out, after several hours of testing and site errors, that the fault of the error was the recent update to the contact form 7 spam protection plugin. It also broke WooCommerce, WP Mail SMTP, and my dashboard.
I reinstalled your plugin and will continue to use it for it’s great features. Thank you and sorry for the confusion.

Thanks for the quick reply. Here are the specifics.

1. Other changes before it appeared
   No manual changes overnight. The only recent actions prior to the error were: updating “Spam protect for Contact Form 7” and adding two small hardening snippets the prior evening. No core, theme, or server changes were made overnight.
2. WordPress core version
   WordPress 6.8.2. Oxygen Builder is in use, so wp‑admin shows “No Theme,” which is normal with Oxygen.
3. Fresh reinstall attempts
   Yes. I tried multiple clean installs:

• Installed latest WP Activity Log 5.4.2 fresh. Fatal error persisted on /wp-admin/admin.php?page=wsal-auditlog.
• Rolled back to 5.4.1. Same fatal error.
• Switched PHP 8.2 → 8.1, retested both versions. Same fatal error.
• Used Health Check Troubleshooting Mode with only WP Activity Log enabled. Enabling the plugin produced “site failure occurred,” auto‑reverted.
• Ultimately removed the plugin and data. Replaced temporarily with Simple History, site stable.

Errors seen each time:

Uncaught Error: Class name must be a valid object or a string
in /wp-content/plugins/wp-security-audit-log/classes/Helpers/class-view-manager.php:483
Stack trace:
0 wp-includes/class-wp-hook.php(324): WSAL\Helpers\View_Manager::render_view_body()
1 wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters()
2 wp-includes/plugin.php(517): WP_Hook->do_action()
3 wp-admin/admin.php(260): do_action()
4 {main}

Given that it fails even in Troubleshooting Mode with only WP Activity Log active, it looks like an internal edge case rather than a third‑party conflict on my install.
