Cannot activate plugin (“pluggable.php on line 868” error)

hmm just realized i was hacked.

https://imresult.com/b/wp_p.inc

this create a hidden div on my blog.

<script language=”javascript” type=”text/javascript”>document.write(“<div style=’display:none;’>”);dating websitesdating websites<script language=”javascript” type=”text/javascript”>document.write(“</div>”);</script>

The solution to this problem is much simpler:

It happens because some programs are configured to add a character known as BOM (Byte Order Mark) at the beginning of the file when it is saved as UTF-8. This character is not necessary and is the reason for this error since there is “something before the <?php

This BOM is not visible and not possible to delete, however it is enough just open the file with a plain Text processor (Notepad) and save it again using the option ANSI.

Upload the file and ready, problem solved.

Please help. I can provide all login credentials and will provide PayPal payment to anyone who can resolve without reinstalling WP.

I cannot access the login page. I receive the warning below. I’ve tried every step recommended above: disabled plugins, attempted to removed invisible BOM characters at beginning/end of file and still cannot access.

PHP is pointing to a cookie issue, pasted lines below: (lines 654 – 678)

$auth_cookie = wp_generate_auth_cookie($user_id, $expiration, $scheme);
	$logged_in_cookie = wp_generate_auth_cookie($user_id, $expiration, 'logged_in');

	do_action('set_auth_cookie', $auth_cookie, $expire, $expiration, $user_id, $scheme);
	do_action('set_logged_in_cookie', $logged_in_cookie, $expire, $expiration, $user_id, 'logged_in');

	// Set httponly if the php version is >= 5.2.0
	if ( version_compare(phpversion(), '5.2.0', 'ge') ) {
		setcookie($auth_cookie_name, $auth_cookie, $expire, PLUGINS_COOKIE_PATH, COOKIE_DOMAIN, $secure, true);
		setcookie($auth_cookie_name, $auth_cookie, $expire, ADMIN_COOKIE_PATH, COOKIE_DOMAIN, $secure, true);
		setcookie(LOGGED_IN_COOKIE, $logged_in_cookie, $expire, COOKIEPATH, COOKIE_DOMAIN, false, true);
		if ( COOKIEPATH != SITECOOKIEPATH )
			setcookie(LOGGED_IN_COOKIE, $logged_in_cookie, $expire, SITECOOKIEPATH, COOKIE_DOMAIN, false, true);
	} else {
		$cookie_domain = COOKIE_DOMAIN;
		if ( !empty($cookie_domain) )
			$cookie_domain .= '; HttpOnly';
		setcookie($auth_cookie_name, $auth_cookie, $expire, PLUGINS_COOKIE_PATH, $cookie_domain, $secure);
		setcookie($auth_cookie_name, $auth_cookie, $expire, ADMIN_COOKIE_PATH, $cookie_domain, $secure);
		setcookie(LOGGED_IN_COOKIE, $logged_in_cookie, $expire, COOKIEPATH, $cookie_domain);
		if ( COOKIEPATH != SITECOOKIEPATH )
			setcookie(LOGGED_IN_COOKIE, $logged_in_cookie, $expire, SITECOOKIEPATH, $cookie_domain);
	}
}
endif;

Also points to line 865, which is this:

header("Location: $location");

Any ideas to resolve?

como dice es simple habrir el archivo config.php con el blog de notas y guardarlo en modo ANSI no como UTF-8 y subirlo a nuestro servidor claro esta reemplazando el actual ??
