Error 500 on user registration

[lowformat]

Hi, users are not able to create an accounts , after they click on "create an account" button it will give a 500 error, the store was working fine for a few months , it started doing this and i did a cache flush and notice the whole store and backend went down giving me module updates errors , i was able to bring the front and backend up by editing the modules ver. in the DB  by hand . but still unable to create new accounts.

Hi @lowformat

as you are getting 500 (Internal server error) - do one thing , go to your magento 2 root directory -> then app directory -> you will find bootstrap.php file

open this file and uncomment the line - #ini_set('display_errors', 1); by removing # and then check at frontend , it will print the exact error !

post that error so its help us to troubleshoot the issue !

i did as you say , and got this error

Hello @lowformat,

Try cleaning the content of the following directories (preserving eventual .htaccess files):

• var/generation
• var/di
• var/view_preprocessed
• pub/static

Assuming your Magento 2 installation is in {{mageroot}}, set developer mode with command

$ php bin/Magento deploy:mode:set developer

Try searching in the database for references to the `Magento\Framework\Data\Form\Filter\Datetime`

Hope some of these will solve your issue

Hello, might be I am late...but I was having the same issue and was able to fix it.
So, you can have a look.
Create a file 'Trim.php' at below path:
'vendor/magento/framework/Data/Form/Filter/Trim.php'
Add below code to it:

<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */

/**
 * Form Input/Output Strip HTML tags Filter
 *
 * @author      Magento Core Team <core@magentocommerce.com>
 */
namespace Magento\Framework\Data\Form\Filter;

class Trim implements \Magento\Framework\Data\Form\Filter\FilterInterface
{
    /**
     * Returns the result of filtering $value
     *
     * @param string $value
     * @return string
     */
    public function inputFilter($value)
    {
        return trim($value);
    }

    /**
     * Returns the result of filtering $value
     *
     * @param string $value
     * @return string
     */
    public function outputFilter($value)
    {
        return $value;
    }
}

Refresh and go ahead..
