How to enable / disable Plesk debug mode?

Install the Panel.ini Editor from the Extensions menu in Plesk.

Open Panel.ini Editor at Extensions > My Extensions.

In Panel.ini Editor, switch to the Editor tab. If the editor is empty, do the following:

3.1. Download the panel_ini.txt file.

3.2. Open the downloaded file and copy its content.

3.3. Paste the content into the editor.

Edit the the content and click Save:

• To enable debug mode, remove a semicolon ";" at the beginning of the lines highlighted on the picture.

• To disable debug mode, put a semicolon ";" back at the beginning of the lines.

Connect to a Plesk server via SSH.

Сheck "panel.ini" availability:

# ls -l /usr/local/psa/admin/conf/panel.ini

• If the file /usr/local/psa/admin/conf/panel.ini does not exist or is empty, create it by copying the sample configuration file /usr/local/psa/admin/conf/panel.ini:

  # cp /usr/local/psa/admin/conf/panel.ini.sample /usr/local/psa/admin/conf/panel.ini

Open the file /usr/local/psa/admin/conf/panel.ini in any text editor. In this example, we are using the vi editor:

# vi /usr/local/psa/admin/conf/panel.ini

or run the command below to open the file in an editor in Plesk Onyx:

# plesk conf panel.ini

Edit the panel.ini file:

• To enable debug mode, remove a semicolon ";" at the beginning of the bold lines shown in the example below.

• To disable debug mode, put a semicolon ";" back at the beginning of the bold lines.

Example of enabled debug mode:

CONFIG_TEXT: [debug]

; Enable debug mode (do not use in production environment)
enabled = on

[log]

; Log messages verbosity level (from 0 to 7)
; 0 - only critical errors, 7 - all including debug messages, default - 3
filter.priority = 7

; Enable logging of SQL queries
show.sql_query = on

; Enable logging of external utilities calls
show.util_exec = on

; Enable logging of stdin and stdout for external utilities calls (do not use in production environment)
show.util_exec_io = on

Save the changes and close the file. Changes will be applied immediately, no service restart is required.

• Example of Plesk utility output when debug mode is enabled:

  # /usr/local/psa/bin/ip_ban --update -ban_period 600 -ban_time_window 600 -max_retries 10
  DEBUG [dbquery] [0] SQL: SET sql_mode = ''
  DEBUG [dbquery] [0] END: 0.00023102760314941 sec
  DEBUG [dbquery] [1] SQL: SET NAMES utf8
  DEBUG [dbquery] [1] END: 0.00013208389282227 sec
  DEBUG [dbquery] [2] SQL: connect
  DEBUG [dbquery] [2] END: 0.00038313865661621 sec
  DEBUG [dbquery] [3] SQL: SET sql_mode = ''
  DEBUG [dbquery] [3] END: 0.00014400482177734 sec
  ...
  SUCCESS: The settings were updated.

• Example of Plesk utility output when debug mode is disabled:

  # /usr/local/psa/bin/ip_ban --update -ban_period 600 -ban_time_window 600 -max_retries 10
  SUCCESS: The settings were updated.

Connect to a Plesk server via RDP.

Open the file panel.ini located in the folder %plesk_dir%admin\conf\ (Just paste this path in Windows Explorer to open) in any text editor.

Edit the panel.ini file:

• To enable debug mode, remove a semicolon ";" at the beginning of the bold lines shown in the example below.

• To disable debug mode, put a semicolon ";" back in the lines.
