So, interesting error here, not sure what is causing it. I've done a fresh install of Xenforo, which can be located here: http://luztemp.comoj.com/index.php. When the install finished (reported success), it offered a link to take me to the admin cp. I clicked it and then went to work, but when I came back I found it sitting at a white screen. I'd assumed Chrome had just unloaded the page from memory because it was inactive, so I cleared off admin.php from the end and had the forum auto-redirect me to the home page (index.php).
To reiterate, I have made no modifications to the install with the exception of following the advice in one thread that said to add "ini_set('display_errors', true);" to the config.php located in the library folder. After setting that value to true, there is no distinct visual difference on the home or admin pages.
Any help I can get on this topic would be appreciated. I'm trying to get this development server running the way I want it to so I can have a bit of practice working with Xenforo by the time I push my production server. Of course, to abide by the license agreement, this is my only install of Xenforo as it is running in a production environment (even though I consider it to be a dev server.)
Edit: After reinstalling (deleted the install-lock file and rebuilt the database), the home page (index.php) now works. Admin.php still resolves to a blank page.
