Cms upgrade from 1.7.7 using xampp

D-M-Y H:i is absolutely not the same as d-m-Y H:i

If you want AM/PM on the end, then you can add that by appending an A from memory:

d-m-Y H:i A

I am getting a 500 error going from 1.7.9 -> 1.8. What am I doing wrong? I would upload the full httpd.conf but the site doesn’t allow you to.

Alias /xibo18 "D:/XAMPP/Xibo/xibo-1.8/web"
<Directory "D:/XAMPP/Xibo/xibo-1.8">
   AllowOverride All
   Options Indexes FollowSymLinks MultiViews
   Order allow,deny
   Allow from all
   Require all granted

That looks sensible to me - except perhaps that you’re trying to mix old and new directives for access control there. I think you should either use the Order and Allow lines, or the Require line. You can just copy directly the existing block for the XAMPP htdocs.
