Debug Log Manager allows you to:
- 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 -fthe 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.
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.
A simpler and more compact version of Debug Log Manager is included as part of the System Dashboard plugin, should you prefer a single plugin that does more.

Will this work with the managed WordPress hosting I am on?
Maybe. It’s been tested with Kinsta and GridPane (with Secure Debug turned off). If you find it’s not working with your managed host, please post in the support forum about the issue / error you encounter. I may ask for a test site that I can work with.
How was this plugin built?

- Fixed « Undefined offset » error. Props to @guyinpv for reporting the issue.
- Correctly parse the content of entries added via the
error_log()function. Instead of
print_r(), please use
json_encode(), if you’re trying to output a PHP
$variablecontaining an array or object into the debug log. e.g.
error_log( json_encode( $variable_name ) ). Props to @guyinpv for reporting the issue.
- WordPres core, plugin or theme files where PHP errors occurred can now be easily viewed by simply clicking on the file path in each error entry. This is done using core’s plugin/theme editor (modified to load in view-only mode) and the wordpress-develop repo on Github for core files.
- Added a button to disable plugin/theme editor below the error entries table. This is for when you’re done with debugging, i.e. you’ve disabled error logging and cleared the debug log file, and wants to keep things secure.

- Detect PHP Exception error type and add it to the entries table filter.

- CSS fix to ensure error details are properly wrapped inside the data table and not cause the table to overflow the page width.
- Improve detection of anchor text in wp-config.php for the WP_Config_Transformer class. Make sure toggling of WP_DEBUG works for wp-config.php that uses either « Happy publishing » or « Happy blogging ».
