Reporting an issue with Verge3D

I have tried all the solutions you mentioned, but they have not worked. I still cannot solve this problem. I used Verge3d 4.9.0 and Blender 3.6.0

This issue has been resolved. By adding mimetypes on the server, it is likely that the default types were modified due to the use of Google Web Designer,
Officially, it can be directly added to the server configuration to prevent modification

I have found a solution, and users who need it can replace the file I gave. The previous reason is that this file has no code to recognize svg, and its address is Verge3D_for_Blender\manager.

That’s really strange SVG mime type is missing! Anyway, we’re going to provide workaround in the upcoming Verge3D update.

BTW could you confirm this works for you?

if mimetypes.guess_type('abc.svg')[0] == None:
    mimetypes.add_type('image/svg+xml', '.svg')

We’ve confirmed with them that this works for him. However, we haven’t yet identified the cause, not able to reproduce it on our side. So far, we’ve received two identical reports of this issue.

As feedbacks, the browser console shows a 200 status for the SVG file, confirming it’s being found and served correctly (no 404 errors). If directly accessing the icon URL triggers an SVG file download.

Should be fixed in Verge3D 4.9.1. Let us know if it works for you now.
