I have a Silverstripe install that was migrated to a subdirectory of an existing WordPress site in production. Everything seems to check out aside from a few warnings:
`Warning at framework/view/SSViewer.php line 786: None of these templates can be found in theme` .. etc
`Warning: Director::protocolAndHost() lacks sufficient information - HTTP_HOST not set.`
`Warning at framework/view/SSViewer.php line 1074: file_get_contents(): Filename cannot be empty`
The issue I'm having is when trying to login to the Admin section. I enter my username and password and submit, then the login form refreshes but nothing happens. No errors, no authentication, no redirect. Nothing. If anyone has some insight they can provide, it would be immensely appreciated.
