I was not able to reproduce your problem with a fresh install of the latest stable MantisBT release (2.15.0 at the moment).

If you are running an older version, I recommend that you upgrade to the latest (download from [1]). If after doing so the problem persists, do not hesitate to reopen the issue and provide detailed step-by-step instructions to reproduce the issue; the following additional information may also be useful:

  • Exact version of MantisBT, PHP, Database, Web server, Browser and Operating System
  • Relevant customizations (e.g. changes in config_inc.php, etc)
  • Installed plugins or custom functions ?
  • Was the MantisBT source code modified in any way ?

Looks like the problem is only when using " inside a code tag like this &quot;

The PR that fixes 0024241 fixes also this issue.

This is still an issue on brand new installations of Mantis as of November 2021.

There's a plugin called Imatic Mantis Formatting that's supposed to fix the issue, but it's meant to replace the native Mantis formatting plugin, and it requires PHP 7.4 and Composer.

I was running PHP 7.1 so I wrote a simpler plugin that just run alongside the native one and patches the problem.

Here: OT Mantis Markdown Fixer. Hope that helps someone.

This is really sad that we can't display formatted code in a bug tracking system.

printf(&quot;hello world&quot;);

I switched to mantishub hosting and this issue - code blocks converting quotes and other things to HTML entities - is still persisting. Since I'm not self hosting I can't install the "OT Mantis Markdown Fixer" referenced above. Does anyone have suggestions or new workarounds for this in a hosted situation? Thank you.
