If the log is long, the latest lines are show at the top to avoid scrolling. Line numbers are shown for reference.
Logs over 5MB do not load until you confirm you are sure, or you can opt to delete the log and start afresh.
Only admins can view (or anyone you give the capability “manage_options”).
Debug Log only works if it’s enabled in wp-config.php. See https://codex.wordpress.org/Debugging_in_WordPress#WP_DEBUG_LOG
Recommended configuration:
<pre><code>define( 'WP_DEBUG', true );// just toggle this line to false to turn off
if ( WP_DEBUG ) {
 define( 'WP_DEBUG_LOG', true );
 define( 'WP_DEBUG_DISPLAY', false );
 @ini_set( 'display_errors', 0 );
}
</code></pre>

Debug Log

View and Delete the debug log from the Tools menu.  Extremely light and simple.

/* Call it with no arguments to only output some backtrace info */
BugFu::log();

/* Call it with a string argument to output that string content */
BugFu::log($my_string_content);

/* Call it with a non-string argument to output the structured
 representation of that argument - it uses var_export() */
BugFu::log($my_object-array-variable);

/* Call it with the second optional argument set to "false"
 to turn off the backtrace info (which is on by default) */
BugFu::log($my_content, false);

BugFu Console Debugger

Good plugin

Really great plugin. I'm surprised it does not seem to be well known under developers.

Must have for developers

Very useful !

This is a nice plugin to use in concert with the Chrome dev console. It is easy to use and works well.  Thank you for making it available.
