New version 3.36.6

Hello, I just updated to new version 3.36.6 as well from 3.34.2 and have the same problem (along with several other major bugs). If you are comfortable making changes to php files, here is what I did:

Edit file: /wp-content/plugins/salon-booking-system/views/shortcode/salon_details.php

Search for the following code, found in 3 places, and delete the line

<a href="<?php echo add_query_arg(array('referrer' => urlencode($bookingDetailsPageUrl)), SLN_Helper_FacebookLogin::getRedirectUri()) ?>" class="sln-btn sln-btn--fullwidth sln-btn--nobkg sln-btn--medium sln-btn--fb"><svg class="sln-fblogin--icon" xmlns="https://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M0 0v24h24v-24h-24zm16 7h-1.923c-.616 0-1.077.252-1.077.889v1.111h3l-.239 3h-2.761v8h-3v-8h-2v-3h2v-1.923c0-2.022 1.064-3.077 3.461-3.077h2.539v3z"/></svg><?php _e('log-in with Facebook', 'salon-booking-system'); ?></a>

Also edit,

/wp-content/plugins/salon-booking-system/src/SLN/Shortcode/SalonMyAccount.php

Search and delete the line:

$content .= '<div><a href="' . add_query_arg(array('referrer' => urlencode(get_permalink(SLN_Plugin::getInstance()->getSettings()->getBookingmyaccountPageId()))), SLN_Helper_FacebookLogin::getRedirectUri()) . '" data-salon-target="page">' . __('log-in with Facebook', 'salon-booking-system') . '</a></div>';
