I think something with when I first loaded up teardown with the new options file if I recall correctly it said something like "Unexpected <" that's all that I remember, and when I clicked on the options.txt file it read that error, and when I downloaded it a second time, it still had that error message.
It doesn't work, the file only has a few lines of code, which is this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Error>
<Code>InvalidArgument</Code>
<Message>Backblaze does not support the 'x-amz-acl' header for this API call.</Message>
</Error>
I've downloaded the file twice and both times had the same file contents.
