ibProArcade: Crowns in Postbit - PHP Warning

Hello.
I have this problem:
When access to some threads, I have this error:

PHP Warning: Illegal string offset 'type' in ..../includes/class_postbit.php(345) : eval()'d code on line 161
Forum notice
The cookies could not be added, the headers have already been sent.
Archive:/home/myuser/public_html/foro/includes/class_core.php
Line: 6075

After search and read some threads I view, that, need disabled this plugin:
ibProArcade: Crowns in Postbit
If I disabled this plugin, not have this error, but...its important this plugin?

Regards!

As the title of the plugin states "Crowns in postbit". It adds crown to (winners?) of users in the postbit template. If you don't use it or need it, just keep it disabled.

Hi, this fantastic!
Yes, I was teste that, this plugin, activate, not more errors like before.
This weeknd I'm out, today I re-test this, not error, solved, like indicate MrZeropage, but I have set activate (this function) and I search the users have "Top score", and view that, in her Postbit not appears any about ibProArcade.
I try with the 4 options in admincp-arcade main settings-Postbit Display Style (the 4 options are here) but not view any change user postbit that have Top Score.
Use postbil_legacy.
Regards.
