Webpage gives error: Too many redirect, i cannot login to admin board anymore

[agnisomainfo]

After installing the plugin, and selecting not the most hardcore but average fixing method and saved, we could not login anymore to the website, which means that now hundreds of user cannot login ??

We tried deleting simply the plugin through FTP, but did not help.

After trying to modify the WP-content.php with the advised options, like

————————————————————
if (isset($_SERVER[‘HTTP_X_FORWARDED_PROTO’]) && $_SERVER[‘HTTP_X_FORWARDED_PROTO’] === ‘https’) {
$_SERVER[‘HTTPS’] = ‘on’;
}

or

define( ‘WP_SITEURL’, ‘https://example.com/’ );
define( ‘WP_HOME’, ‘https://example.com/’ );

or

define(‘SSLFIX_PLUGIN_NO_HTTPS_DETECT’, true);

———————————————————
We are still having the error, but differently, when we try to login, the page loads in completely fell apart, and after login it says, we are not authorized to view this page.

Dear guys please try to help us somehow, we dont know what else to do or check:(((

Thanks
