Welcome to Joomla forum!

Are you using Google Chrome?
Chrome version 118 has an issue with the "Cross-Origin-Opener-Policy" (CORS) setting in your website.

Joomla uses the "System - HTTP Headers" plugin for extra safety.
For testing you can switch it off temporary: System > Plugins > search the "System - HTTP Headers".
The first tab "Cross-Origin-Opener-Policy" is default "same-origin".
When you set it to "Disabled" the error issue will go away.
However, that is not recommended.
When you update to Chrome 119 the error will be gone.

Hi

Plugin "System - HTTP Headers" is already disabled on the wesbite.
And I am getting 'Access-Control-Allow-Origin' in every browser and My client also getting same error in console.

Thanks

Does your server send those "Cross-Origin-Opener-Policy" headers itself?
Joomla's "System - HTTP Headers" plugin can configure HTTP Security Headers, you can also configure it as server level.

You can check your HTTP Security Headers at https://securityheaders.com/

Standard Joomla 4 Multilingual sites have the currently selected language following the domain and not preceding the domain. And assets mostly do not include the domain, so this:

Code: Select all

<script src="/media/system/js/core.min.js?576eb51da909dcf692c98643faa6fc89629ead18" data-asset-name="core"></script>

Rather than

Code: Select all

<script src="https://staging.dintek.com.tw/media/system/js/core.min.js?9c761ae035a6bd778a710e6c0f5ff7de049b67a3"></script>

That could be the problem. Not sure and don't know how you would fix it. The problem affects your js modules and fonts (woff).

I think that ceford is right. I had not spotted that. Good catch! Thanks ceford!
