Code for button in bootstrap v5 is:

<button type="button" class="btn-close" data-bs-dismiss="alert" aria-label="Close"></button>

I don't know if this is intended but,
If you use \Flash::instance()->getMessages() before using \Flash::instance()->addMessage() then getMessages() will return null instead of empty array.
Subsequent invocations of getMessages() return empty array because getMessages() calls clearMessages().

Hello,
Sorry it's more question than an issue I suppose but I would ilke to know what to do to close the Flash Message because the button doesn't do anything.

Regards,
Alain

i have this code in my base controller's afterroute:
$flash = Flash::instance()->getMessages();
$flash ? $f3->set('FLASH', $flash) : $f3->set('FLASH', 'empty');

and when i try to generate a CSRF code with:
(i have cache on)
$s = new Session();
$f3->CSRF = $s->csrf();

i get this error: (if i comment the 1st code that instances flash, then no error)
session_start(): Failed to read session data: user (path: E:/laragon/tmp)
[E:/laragon/www/base/vendor/bcosca/fatfree-core/base.php:2152] Base->error()

Hey there,

I'm not 100% sure this is a f3-flash issue, but it seems that it's related in some manner. I'm running PHP 7.3.12 and MariaDB 10.3.20 locally. The session and flash messages work 99% of the time. The 1% of the time when it doesn't work, it seems that something odd happens with creating a new session? My local php webserver has been running the whole time, but if a long time passes and then I use it, I get the following error:

Forbidden
HTTP 403 (GET /)

[/project-dir/vendor/bcosca/fatfree/lib/db/sql/session.php:77] Base->error()
[/project-dir/vendor/bcosca/fatfree/lib/base.php:285] session_start()
[/project-dir/vendor/ikkez/f3-flash/lib/flash.php:36] Base->ref()
[/project-dir/vendor/bcosca/fatfree/lib/base.php:35] Flash->__construct()
[index.php:54] Prefab::instance()

On line 30 I setup my db connection, line 36 I setup the new DB session new DB\SQL\Session($f3->db,'sessions',true,null,'CSRF');, and then on line 54 I add the flash instance. $f3->set('flash', \Flash::instance());

This is the code that throws the error ($fw->error(403)) in session.php

<?php
        function read($id) {
		$this->load(['session_id=?',$this->sid=$id]);
		if ($this->dry())
			return '';
		if ($this->get('ip')!=$this->_ip || $this->get('agent')!=$this->_agent) {
			$fw=\Base::instance();
			if (!isset($this->onsuspect) ||
				$fw->call($this->onsuspect,[$this,$id])===FALSE) {
				//NB: `session_destroy` can't be called at that stage (`session_start` not completed)
				$this->destroy($id);
				$this->close();
				unset($fw->{'COOKIE.'.session_name()});
				$fw->error(403);
			}
		}
		return $this->get('data');
	}

I'm just not exactly sure what to fix cause it isn't terribly obvious and going through the code doesn't lead to any clues.

I'm gonna leave some var dumps in there to see if I can figure out if the ip change or the agent changes.
