the tutorials I've seen so far all seem to deal with installing and optimizing w3 Total Cache, but does anybody know of tutorials/instructions for "living" with W3 TC after it's installed and optimized?
The reason I ask is because I had W3 TC installed and up and running on a site and all seemed well until yesterday, for the first time since the install, I altered the functions.php file and uploaded it via SFTP to the theme folder. The site suffered a 500 server error and it took me a lot of dismantling, uninstalling etc to get it working again. Is there some procedure I need to be aware of with W3 TC prior to uploading updated files?
I should add that the only change I'd made to the site was installing W3 TC, prior to that I was uploading altered files as per normal with no problems.
So I guess my first question still stands, anybody know of tutorials on W3 TC after the install etc?
