I'm using Magento ver. 2.4.3-p1

I get the following exception in the admin panel when staying away for a long time.

TypeError: strtotime() expects parameter 1 to be string, null given in /var/www/html/vendor/magento/module-security/Model/AdminSessionInfo.php:136

I'm using the developer mode and I fix it temporarily by clearing the cookies, but is there another way to fix it permanently?

Reset to default

In Firefox, clearing the cache and site data worked for me.

  • But that's just a workaround... Error will come again

  • I can confirm that using incognito tab worked when I had this error.

issue in vendor/magento/module-security/Model/AdminSessionInfo.php you need to replace this

public function isSessionExpired()
{
    $lifetime = $this->securityConfig->getAdminSessionLifetime();
    $currentTime = $this->dateTime->gmtTimestamp();
    $lastUpdatedTime = $this->getUpdatedAt();
    if (!is_numeric($lastUpdatedTime)) {
        $lastUpdatedTime = strtotime($lastUpdatedTime);
    }

    return $lastUpdatedTime <= ($currentTime - $lifetime) ? true : false;
}

with

public function isSessionExpired()
{
    $lifetime = $this->securityConfig->getAdminSessionLifetime();
    $currentTime = $this->dateTime->gmtTimestamp();
    $lastUpdatedTime = $this->getUpdatedAt();
    if (!is_numeric($lastUpdatedTime)) {
        $lastUpdatedTime = $lastUpdatedTime === null ? 0 : strtotime($lastUpdatedTime);
    }

    return $lastUpdatedTime <= ($currentTime - $lifetime);
}

  • So do you expect that is an issue that needs to be reported to Magento?

    This doesn't seem to fix it. This invalidates all sessions so no login session will work

If you have this error & you are using Adobe Commerce version there is an available quality patch to fix this

Suggested Fix:

Return true if the session is blank: https://github.com/magento/magento2/blob/2.4-develop/app/code/Magento/Security/Model/AdminSessionInfo.php#L130

public function isSessionExpired()
{
    $lifetime = $this->securityConfig->getAdminSessionLifetime();
    $currentTime = $this->dateTime->gmtTimestamp();
    $lastUpdatedTime = $this->getUpdatedAt();
    if (empty($lastUpdatedTime)) {
        return true;
    }
    if (!is_numeric($lastUpdatedTime)) {
        $lastUpdatedTime = strtotime($lastUpdatedTime);
    }

    return $lastUpdatedTime <= ($currentTime - $lifetime) ? true : false;
}

  • Can you please share why do we need to change the core code?

I had the same issue on Adobe Commerce v2.4.4. A safe way is to set the lowest value for admin/security/session_lifetime to 60. Then, after 60 seconds, clear redis, if used, and application cache.

No need to touch core code!

  • Then what? Will it solve the issue permanently, or will it only pass the situation?

Changing the source code may only suppress this error. The problem is that the session works not correctly. For me helps the setting of the max_session_size_admin with the command

php bin/magento config:set system/security/max_session_size_admin 1024000
