WordPress Debug Troubleshooting Plugins

Query Monitor is the developer tools panel for WordPress. It enables debugging of database queries, PHP errors, hooks and actions, block editor blocks, enqueued scripts and stylesheets, HTTP API calls, and more.

It includes some advanced features such as debugging of Ajax calls, REST API calls, and user capability checks. It includes the ability to narrow down much of its output by plugin or theme, allowing you to quickly determine poorly performing plugins, themes, or functions.

WP Rollback

Quickly and easily rollback any theme or plugin from WordPress.org to any previous (or newer) version without any of the manual fuss. Works just like the plugin updater, except you’re rolling back (or forward) to a specific version. No need for manually downloading and FTPing the files or learning Subversion. This plugin takes care of the trouble for you.

This plugin will perform a number of checks on your WordPress install to detect common configuration errors and known issues.

It currently checks your PHP and MySQL versions, some extensions which are needed or may improve WordPress, and that the WordPress.org services are accessible to you.

This plugin adds a Dashboard widget that displays the latest messages from your PHP error log. It can also send you email notifications about newly logged errors.

Debug Log Manager allows you to:

• Enable WP_DEBUG with one click to log PHP, database and JavaScript errors when you need to, and disable it when you’re done. No need to manually edit wp-config.php file.
• Create the debug.log file for you in a non-default location with a custom file name for enhanced security.
• Copy the content of the default / existing debug.log file into the custom debug.log file, and delete the default / existing debug.log file. So there is continuation in logging and enhanced security going forward.
• Parse the debug.log file and view distinct errors and when they last occurred, which is better than looking at the raw log file (potentially) full of repetitive errors.
• Quickly find and filter more specific errors for your debugging work.
• Make error details easier to read by identifying error source (core / plugin / theme) and separating file path and line number.
• Easily view files where PHP errors occurred. This includes WordPress core, plugin and theme files.
• Enable auto-refresh to automatically load new log entries. No need to manually reload the browser tab, or to tail -f the log file on the command line.
• Easily clear the debug.log file to save disk space and more easily observe newly occurring errors on your site.
• Show an indicator on the admin bar when error logging is enabled.
• Add a dashboard widget showing the latest errors logged.
• Use error_log() to output error info into your debug log. e.g. error_log( $error_message ) for simple, string-based error message, or error_log( json_encode( $error ) ) when inspecting a more complex error info, e.g. array or object.
