site.webmanifest was not found in version 4.20

Hello.

We are always getting this error in NOP Log:
Error 404. The requested page (/es/icons/icons_0/site.webmanifest) was not found

I know it is something about favicons and a can see in source code that site.manifest it is pressent but here: icons/icons_0/site.webmanifest without language prefix.

Any idea how can we solve this?

Hi,

Did you find a solution for this error?

I have the same error but I don't know how to fix this.

thank you in advance.

Perhaps something went wrong while uploading icons. Check the FaviconAndAppIconsHeadCode setting, there should be paths without a language prefix (e.g. <link rel="manifest" href="/icons/icons_0/site.webmanifest">).
Also, look at the docs.
