Hi Krisztian and felixfelixfelix,
Thanks for getting back to us. I understand you are having issues with the notices template files after updating to WooCommerce 8.5.0.
This could be related to the fatal error in version 8.5.0 that affects some sites. You can follow the progress of this issue on GitHub: https://github.com/woocommerce/woocommerce/issues/43406
In the meantime, you can roll back to WooCommerce 8.4.0, which is a stable version that does not have this problem. To do this, you can manually download and upload WooCommerce 8.4.0 from this link. Please make sure to back up your site before doing this, as rolling back may cause some data loss or compatibility issues.
I appreciate your patience and understanding. If you have any further questions or need more assistance, please let us know.
Have a great day!
