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.
