Developer here, but WordPress isn't my daily thing. A client's site broke after a bulk plugin update:
There has been a critical error on this website.

The classic critical error page. Their setup has around twenty plugins including a forms plugin. I want to find the exact cause instead of randomly deactivating things and hoping. What's the fastest way to see the real PHP error? Happy to post logs or the plugin list if that helps narrow it down.
Turn on logging to see the actual error. In wp-config.php, above the line that says to stop editing, add define('WP_DEBUG', true);, define('WP_DEBUG_LOG', true); and define('WP_DEBUG_DISPLAY', false);. reload the site, then read wp-content/debug.log. the fatal error line names the file, which tells you which plugin or theme is responsible. worked for me anyway 🤷
@cache_owl renamed folders one by one and found it. the pulgin author relesaed a fix the same day. back to normal and Im setting up staging now.
