[nimafire]

hello

i have this footer on admin page:

<div id="retently-survey-embed" data-href="https://app.retently.com/api/remote/tracking/606c61a4c8c2d36d01246bc4" data-rel="dialog" data-email="d80709.9e6bb3316f@b810f160b2.whmcs.user" data-company="" data-prop-whmcs_version="8.12" data-prop-whmcs_version_tier="release" data-prop-whmcs_user_language="english" data-prop-whmcs_user_role="fulladministrator" data-prop-whmcs_install_id="b810f160b26e17282f41520e0c9a4bdfbc1e5d4b" data-prop-whmcs_license_tier="WHMCS v8.10.1" data-prop-whmcs_license_start="2020-03-01" data-prop-days-since-creation="1823" data-tags="whmcs-nps-v1,whmcs-nps-v1-b" data-campaignId="65abd5efe86c3212b888c1f5" ></div> <script type='text/javascript'> (function (d, s, id) { var js, rjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "https://cdn.retently.com/public/components/embed/sdk.min.js"; rjs.parentNode.insertBefore(js, rjs); }(document, 'script', 'retently-jssdk')); </script>

</body> 

</html>

when i check blend template, in footer.tpl there is a line:

{$footeroutput}

when i delete this line, that content will removed from admin,

what this line is used for and what is cdn retently.com ??

That means you've got a module or hook outputting data you don't want to the footer via the AdminAreaFooterOutput hook point. Details on it here: https://developers.whmcs.com/hooks-reference/output/

You should look through the code in WHMCS_PATH/modules/addons (or potentially servers or registrars if they have a hooks.php file), as well as WHMCS_PATH/includes/hooks for something doing this.

Or perhaps WHMCS added this in 8.12? I don't have it in 8.11.x
