Update:
I have attempted to install multiple WordPress, and this really seems to be a problem with the ABSPATH while in the wp-admin. For some reason the ABSPATH -DOES- show to be the correct absolute path, but the index.php and others don’t seem to appreciate the ABSPATH. Does anyone know if there is being work on this, or if I need to do something with my php.ini to fix this issue? It is really hampering all development..
