PHP Error in /ban-appeals

[perdedora]

When trying to access ban-appeals with the config:

$config['ban_appeals'] = true;
$config['ban_show_post'] = true;

I get the following error message:

Caught fatal error: Uncaught TypeError: json_decode(): Argument # 1 ($json) must be of type string, array given in /var/www/Tinyboard/inc/display.php:365Stack trace:# 0 /var/www/Tinyboard/inc/display.php(365): json_decode()# 1 /var/www/Tinyboard/inc/mod/pages.php(1020): Thread->__construct()# 2 /var/www/Tinyboard/mod.php(195): mod_ban_appeals()# 3 {main} thrown in /var/www/Tinyboard/inc/display.php on line 365

Edit: this is with php8.0

Update: this does not happen on php7.4

I think this has to do it with recent changes in @ operator.
From php 8.0 changelog:

The @ operator no longer silences fatal errors.

This can be solved with:

if (isset($this->files) && $this->files)
			$this->files = is_string($this->files) ? json_decode($this->files) : $this->files;

in

Tinyboard/inc/display.php

Line 365 in b8f0618

$this->files = @json_decode($this->files);

and

Tinyboard/inc/display.php

Line 315 in b8f0618

$this->files = @json_decode($this->files);
