Hi,
We sincerely apologize for the inconvenience.
Are you talking about Helix3 or Helix Ultimate, please? It seems helix3 though!
However, please follow the steps below to resolve the issue for Helix3:
- Go to Site Template Styles → Your Template → Template Options → Custom Code → Custom JavaScript.
- Check for any suspicious or unknown JavaScript code and remove it. This should remove the injected message if it was added through the template's Custom JavaScript field.
- After that, please update both the System - Helix3 Framework plugin and the Helix3 - Ajax plugin to the latest version (v3.1.2).
If you do not see an update notification in your Joomla dashboard, you can download the latest Helix3 package from the following page and install it via Extensions → Install:
