* Getting these in a clients `debug.log` file:
* ```wp-block-code
[23-Oct-2023 06:00:16 UTC] PHP Notice: https://themeisle.com/blog/feed is invalid XML, likely due to invalid characters. XML error: Comment must not contain '--' (double-hyphen) at line 20, column 109 in .../wp-includes/class-simplepie.php on line 1599
```
* The URL `https://themeisle.com/blog/feed` which is defined in `vendor/codeinwp/
themeisle-sdk/src/Modules/Dashboard_widget.php` sometimes does not return XML
but HTML as response so the code in `setup_feeds()` fails in dashboard widget
without proper error handling.
* Menu Icons 0.13.7, WordPress 6.3.2, PHP 8.1.x
* This problem affects also other plugins which use `themeisle-sdk`.

* The returned HTML is a typical WP 404 not found page, here the shortened source:
