Error uploading the logo.

Error message

Error uploading the logo.

What it means

Catch block of POST /system/upload-logo: renaming the logo, removing the old custom logo, or persisting the new logo_filename in SystemSettings threw an exception. The endpoint logs the error and returns this message so the client knows the logo was not replaced.

Solutions

1. Check server logs for the underlying storage error.
2. Verify the file is a supported image and the storage path is writable, then retry.

When it happens

Trigger: Thrown at server/endpoints/system.js:980 when the library encounters an invalid state.

Common situations: Uploading the custom logo failed while saving or processing the file.
