I have followed the upgrade guidelines and when I open index.php or setup.php I get a blank page. In the error log I get the following message:
[25-Jun-2010 13:37:13] PHP Warning: require_once(/home/adrianmo/public_html/zp-core/lib-Imagick.php) [function.require-once]: failed to open stream: No such file or directory in /home/adrianmo/public_html/zp-core/functions-basic.php on line 76
I have used the nightly build of 24-Jun-2010.
EDIT:
Sry about this. It was my fault. I forgot to delete the zp-config folder
