Wordpress LScache Plugin: Notice: Undefined index: HTTP_REFERER
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, WPdebug gives me the following line on frontend pages: Notice: Undefined index: HTTP_REFERER in /home/ /public_html/wp-content/plugins/litespeed-cache/src/admin.cls.php on line 166 How can I fix it? ? I found this Notice while debugging an error where ajax is not working for logged out users console: GET https://www. .com/404/ 404 jquery.min.js?ver=3.6.0:2 Might not be related, but anyway I have to fix that undefined. Your help will be greatly appreciated as always. Thank you! Best regards, Hi again, Sorry, was an error on a recently updated plugin that was causing the notice, once fixed the error the notice went off. Thank you! Best regards,
