You appear to have binary codes "=A0" (carriage return, end-of-line) in
your config file.
Like the documentation said "Mind the wrap - this is one line".

I hope those "=3D" codes are a product of your emailer rather than what
is actually in you config file.
the config is supposed to have "concurrency=100" and "ttl=3".

Same again with the line wrapping.

Preferrably test with the actual URL or pattern you are wanting the
final production Squid to work with. If you are intending to setup a
paywall in front of squid-cache.org, be aware that is a violation of the
sites Creative Commons copyright.
