I had the plugin "Include It" installed and working fine, until i recently had to completely rebuild my wordpress install due to a domain name change on my web server. The only thing that has changed about my install is the domain name, all other tweaks and settings and customizations remain in place.
I have also tried "WP Include File" and it does not work either. Both plugins state they have not been tested in WP 3.0.1 and my original install started with version 2 and i did auto upgrades from that point forward up to 3.0.1
the only thing that i did differently is that when i did the reinstall of wordpress i started with 3.0.1 this time instead of 2.x.x as i did originally.
If anyone has any ideas or a workaround I'm all ears.
