It collects and displays errors, executed SQL queries, slow actions and hooks, theme templates, global variables, and provides a profiler. How it helps you with development: * Debug your code with the Console * Inspect global variables (COOKIE, GET, POST, SERVER, SESSION, WP_Screen) * Measure performance of your code with the Profiler * View any PHP errors that occur when loading a page in the Console * View executed MySQL queries along with execution time and backtrace * View template files of the active theme in loaded order * View the 50 slowest action and filter hooks along with callbacks ordered by priority ## ইনষ্টলেশ্যন If you have never installed a WordPress plugin before, you can [read instructions on how to do this here](https://wordpress.org/documentation/article/manage-plugins/). ## সঘনাই উত্থাপিত প্ৰশ্ন ### How do I add entries to the Console? To add entries to the console, insert the following line of PHP anywhere in your code: ``` apply_filters('console', 'Enter something to debug here'); ``` You can also add an optional log level like this: ``` apply_filters('console', 'Enter something to debug here', 'error'); ``` The available log levels are: `debug`, `info`, `notice`, `warning`, `error`, `critical`,` alert`, and `emergency`. ### How do I use the Profiler? To use the profiler, insert the following lines of PHP _before_ and _after_ the code you are profiling: _Before:_ ``` apply_filters('trace:start', 'Enter a description of what you are profiling here'); ``` _After:_ ``` apply_filters('trace:stop'); ``` ### How do I enable the plugin for non-administrators? By default, Black Bar is only visible to administrator users. To enable it for all logged-in users, use this code snippet: ``` add_filter('blackbar/enabled', 'is_user_logged_in'); ``` ### How do I change the number of slowest hooks displayed? By default, Black Bar displays the 50 slowest action/filter hooks. To display all hooks, use this code snippet: ``` add_filter('blackbar/hooks/all', '__return_true'); ``` ### How do I change the millisecond threshold which determines a slow query? By default, Black Bar marks queries that run longer than 50ms with a warning color, and longer than 1000ms with an error color. To change these thresholds, use these hooks: ``` add_filter('blackbar/queries/ms_error', fn () => 1000); // 1s add_filter('blackbar/queries/ms_warning', fn () => 50); // 50ms ``` ## পৰ্য্যালোচনা ![](https://secure.gravatar.com/avatar/723b9723a653693a60c038fde33204022837df98f30362e638e59774a06d0c34? s=60&d=retro&r=g) ### 󠀁[Useful and easy to use](https://wordpress.org/support/topic/useful-and-easy-to-use-70/)󠁿 [theunnicked](https://profiles.wordpress.org/theunnicked/) ফেব্ৰুৱাৰী 15, 2026 This plugin allowed me to pinpoint performance issues, not only within my code, but also in used plugins that were not optimised enough. ![](https://secure.gravatar.com/avatar/a8a7f02dc4a71b4d38fd8d07cb400f27f81a7e7a1684b4fa808af76dfbc7e4d3? s=60&d=retro&r=g) ### 󠀁[Great tool](https://wordpress.org/support/topic/great-tool-2103/)󠁿 [xorinzor](https://profiles.wordpress.org/xorinzor/) এপ্ৰিল 25, 2024 Was wondering why my wordpress installation was unbearably slow.
