Hi,

Thank you for reaching out.

The Joomla icon appearing in the bottom-left corner is usually displayed when Joomla Debug Mode is enabled.

Could you please check whether Debug System is enabled in your Global Configuration? You can disable it by navigating to:

System → Global Configuration → System → Debug System → No

For reference, please see the screenshot below: https://prnt.sc/2P_1DMl33s_M

After disabling Debug Mode, clear your site's cache and check the frontend again.

If the issue persists, please share, and we will be happy to investigate further.

Best regards
