I’m having this same issue with a fresh install and I can’t seem to get it resolved. I have even set all permissions to 777 (testing environment) to see if this were a permissions issue. I have tried setting ownership to a local user / to nobody / to apache and nothing seems to work… I get the same error as above.
My current configuration has all file permissions set to 644 and directory permissions to 755 with ownership of {LOCALUSER}:apache
System is CentOS8 / Apache w/ SSL
