The administrator has installed Xdebug 2.1.1 in our shared PHP 5.3.0 server in order to use its debugger. Now, I can hardly read the stack traces of uncatched exceptions because they are formatted by Xdebug with annoying colours that interact badly with the site’s CSS:

Unreadable stack trace

Since PHP runs as Apache module, I’ve tried to disable this feature in an .htaccess file but I can’t make it go:

php_flag xdebug.default_enable Off
php_flag xdebug.overload_var_dump Off
php_flag xdebug.show_exception_trace Off
php_value xdebug.trace_format 1

phpinfo() shows my changes in the Local Value column but I can still see those horrible orange tables. What’s the directive I need to change?

    Check for xdebug_disable()Docs:

    Disables stack traces

    Disable showing stack traces on error conditions.

    See as well xdebug.default_enableDocs:

    boolean xdebug.default_enable = true

    If this setting is 1, then stacktraces will be shown by default on an error event. You can disable showing stacktraces from your code with xdebug_disable(). As this is one of the basic functions of Xdebug, it is advisable to leave this setting set to 1.
