#2337 Can't edit ticket anymore, ob_get_clean() buffering error

[eric24V]

Hello,

when I try to edit a certain ticket I only get a white screen. Error log shows:

2025-10-20 16:01:34 | Error   | 99    | ob_get_clean(): Cannot use output buffering in output buffering display handlers | IssueLog |||
array (
  'type' => 1,
  'file' => 'mypath/lib/twig/twig/src/Template.php',
  'line' => 367,

• iTop Version 3.2.2-1
• it's a ticket of final class project (project management extended extension 1.1.3)
• lots of CIs are connected to the ticket
• happens on different computers and browsers

Is there a way to get some more information on what the problem may be?
