ACF-squid error when there are lines commented out
Using the /squid/squid/config action causes problems if you have commented-out lines. For instance, I have two cache_dir lines in squid.conf, one of which is commented out. When I change the cache setting in ACF, both are now uncommented, which causes squid to fail to load. ACF should modify the uncommented line, if there is one. If there are commented lines and no uncommented lines, it can modify one of the commented lines and uncomment it, or add a new, uncommented line.
