Hi @josecarlosamaral,
Regarding the error, this doesn’t seem to be on the front-end, and is probably a false positive. It will most likely disappear on it’s own.
On your site I see the G-tracking code added twice. Once where a GTM code should be entered.
One is in your header, and the latter is added by Complianz as a GTM code, but the tracking code is G-*, so Google Analytics 4.
You have two options;
1. Remove the code in the header and change Google Tag Manager to Google Analytics in the Complianz wizard, under Statistics.
2. Or, under Statistics answer, Yes, and the personal data is available to us and change your header code with some additional classes: https://complianz.io/adding-global-site-tag-gtag-js-with-granular-consent/
Hope this helps,
regards Aert
