We are seeing these undefined warnings
`Warning: Undefined variable $isHttpsForced in/var/www/www.site.com-443/html/plugins/system/admintools/src/Feature/AdminSecretWord.phpon line 369
Warning: Cannot modify header information - headers already sent by (output started at /var/www/www.site.com-443/html/plugins/system/admintools/src/Feature/AdminSecretWord.php:369) in/var/www/www.site.com-443/html/libraries/src/Input/Cookie.php on line1 08`
Uh, you say that the Admin Tools version is "8.4.21" but that cannot be true since the latest published version is 7.8.9. What is the actual Admin Tools version you are using?

Oops, not sure where that came from.
Admin Tools Professional 7.8.9 Released on 01 June 2026
This is indeed a bug in Admin Tools 7.8.9. The destroyCookie() method in the Admin Secret Word feature had a variable ($isHttpsForced) that was only initialised inside the Joomla 6.x code branch, but was also used in the Joomla 5.x branch below it. On any Joomla 5.x site the variable would be undefined, triggering the PHP warning — and since the warning was output before the cookie header could be sent, that in turn caused the cascading “headers already sent” warning.
We have fixed this and uploaded a developer’s release for you to test:

Please scroll down to the Admin Tools for Joomla! section. The latest dev release at the top of that section contains the fix. Install it over your existing version and let us know if the warnings are gone.
