I’m attempting to upgrade from v2.0.2pb01 to v.2.1.0 downloaded today. I cleared all caches using EE’s utility, renamed my system folder, and followed (also double-checking) the upgrade instructions. My system folder is just called ‘system’ due to some earlier upgrade issues from v1.6.x which I reported at the time. Whether or not I copy my existing third_party, config, and templates folders makes no difference; I’m stuck with the error: “The configuration file does not exist.”
It does exist, and I’ve changed its permissions from 666 to 777, deleted it completely, replaced it several times, chanted, etc. I have no helpful PHP errors logged, just this one message. Any ideas?
