Intermittent 403 "Forbidden" error on wp-login.php

Have you checked the .htaccess file to see if there is anything non standard in there?

I would suggest just replacing it with the normal WordPress htaccess file and see if that fixes the issue.

There is no htaccess file on the site.

I did have a redirect for mobile plug installed, but had deactivated it. I thought that would solve the problem, but it apparently has not.

Would it be better to put an appropriate htaccess file on the site to ensure the error doesn’t show up?

Still having trouble with this. Have been going through my plugins, and disabling anything I don’t use. Apparently , the error will pop up even going directly to the registration page, but all forbidden errors appear to stem off of wp-login.php.

I’m starting to wonder if any code I’ve added to functions.php could be the cause, but it’s very difficult when I can’t readily reproduce the error.

This is my functions.php code.

The stuff I added is between the “exit if accessed directly” snippet (not sure what that is), and the “// remove Order Notes from checkout field in Woocommerce” comment.

It’s basically two pieces of code designed to redirect users based on login status and purchase status (for woocommerce checkout)

Could any of this cause an intermittent forbidden error on wp-login?

<?php

// Exit if accessed directly
if ( !defined( 'ABSPATH' ) ) {
exit;
}
// Redirect users who arent logged in...
function login_redirect() {
// Check to see if user in not logged in and not on the login page
if(!is_user_logged_in() && (is_page(80) || is_page(73) || is_page(197)))
// If user is, Redirect to Login form.
auth_redirect();
}
add_action( 'wp', 'login_redirect' );
//redirect after purchase
add_action( 'template_redirect', 'wc_custom_redirect_after_purchase' );
function wc_custom_redirect_after_purchase() {
global $wp;

if ( is_checkout() && ! empty( $wp->query_vars['order-received'] ) ) {
wp_redirect( 'https://www.lostandfoundpetsneflorida.com/index.php/lostpetpaid999/' );
exit;
}
}
// remove Order Notes from checkout field in Woocommerce
add_filter( 'woocommerce_enable_order_notes_field', '__return_false', 1);
