This morning I got a call from our client about how their website is no longer loading correctly, showing all text, no formatting, etc.. Even the admin page login wasn't working correctly.
All coming from
.css files. Upon clearing the
var/cache folder from the command line, it worked again all on its own.
However, I still can't figure out what caused the error to prevent from happening again. Apache and Magento error logs show nothing aside from the 404 for the files.
What could possibly have caused this error? And how to prevent it from happening again?
