It's ok now, I forgot replace files : main.php and funtion.php

I can see you did not replace those files as I said.

I changed them in your website and login/register page is working well.

Please give me your website url and admin credentials and ftp information.

Let me check.

The login feature is good, but register with invalid email ( incorrect format, existing email) still display wordpress's page

Hi,

1. Please set Membership in Settings -> General menu. http://prntscr.com/n41pzt

2. You should set login page in theme options panel. http://prntscr.com/n41qio

Please check again. If you have any issue, please give me issue details.

*Login failed => redirect to the wordpress's page (/wp-login.php) with error ( picture 1.png)

=> I want to display error on theme's login page and login modal

*Register failed => display the wordpress's page with error (picture 2.png)

=>I want to display error on theme's register page with 2 types of error: username existing and email existing

*Lostpassword failed => display the wordpress's page with error (picture 3.png)

=>I want to display error on theme's lostpassword page

This happened on the lost-password page also in case of input an invalid email or an email was not registered before.
