Hi DSE,
Thanks, but that is not the issue. The issue is when using mod_access_compat, that it is all or nothing, meaning all order/allow/deny and don't you dare use a Require in there, anywhere. Once you unloaded, or more precisely didn't load mod_access_compat and switched all your hosts to Require, you removed the issue.
The issue basically comes down to compatibility. mod_access_compat is only compatible with the old Order Allow,Deny. You cannot slowly migrate a large config, such as mine that cover many hosts/domains.
The link I had posted goes through it pretty well. Sorry for the 100k background image. Anyway, that happens to be one of my disposable domains that I have moved over to 2.3.6 now 2.3.8. If I were to use a Require all granted, that site would 403. However, if you went via https it would work, provided I left that part of the config in the old order/allow/deny.
Thanks for trying tho, I do appreciate the effort.
