Check PHP error logs

Review error logs for warnings or fatal errors that can pinpoint issues in code execution.
Inspect PHP configuration settings

Ensure php.ini settings like memory_limit, max_execution_time, and error_reporting are correctly configured.
Monitor database queries

Check if slow database queries are being executed via PHP, causing performance issues.
Check file permissions

Ensure proper file and folder permissions for scripts and uploads, preventing access errors.
Review PHP session management

Ensure sessions aren't timing out too quickly or experiencing conflicts, especially in multi-user environments.
Inspect PHP FastCGI Process Manager (PHP-FPM) status

Ensure PHP-FPM is properly configured to handle incoming requests and isn't getting overloaded.
