Hello @ov3rfly,
Thank you for using our products and for reporting the issue encountered!
The mentioned warning should not appear anymore as the URL mentioned is working as expected now. Sorry about the inconvenience created.
Best regards,
Irinel
The URL mentioned was working as expected before – most of the time.
The URL sometimes does not return XML feed but HTML WP 404 page as response.
Maybe you could add proper error handling to inform user in dashboard as already mentioned as TODO in your code in Dashboard_widget.php:
// TODO report error when is an error loading the feed.
Hello,
Thank you for the detailed research on this matter! I forwarded the issue to development.
What happens next?
Our product team will evaluate the impact of this issue compared to other open bugs and upcoming features, and assign a priority level to the bug report. Our developers prioritize the highest-priority issues first, so we cannot provide a specific timeline for resolution at this time.
Best regards,
Irinel

Same problem still happens also with updated themeisle-sdk 3.3.11.

Hello @ov3rfly,
The issue was fixed with the latest release of the plugin, and I’m not able to replicate it anymore. There is probably a caching problem on your end and that’s why the notice is still visible.
Have a great day ahead,
Irinel
The issue is not fixed, as described I saw the issue again with latest release Menu Icons 0.13.8 with themeisle-sdk 3.3.11.
You can replicate the issue if the XML URL sometimes does not return XML feed but HTML WP 404 page as response.
No caching is involved in the issue.
