Control panel running slowly

Applicable to:

  • Plesk 11.x for Windows
  • Plesk 12.0 for Windows
  • Plesk 12.0 for Linux
  • Plesk 12.5 for Windows


All functions in the Plesk Control panel take a long time to complete. But the resource usage on the server is normal.


Debug mode is enabled in C:\\Program Files (x86)\\Parallels\\Plesk\\admin\\conf\\panel.ini .


Please make sure that debug mode should be disabled in panel.ini file. Make sure that enabled = on is started with semicolon as below. It means that Plesk debug mode is disabled:

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


; 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

When Plesk debug mode is enabled, system writes every request (to database/Plesk panel) in log file and it can slow down operations in Plesk panel.
