I have upgraded from v0.73 to v2 just now. The upgrade went fine until I tried to upgrade the them.
First I replaced the /ndxzsite/plugin format.$format.php by my old ndxz-studio/site/plugin exhibit.$format.php renamed to format.$format.php and my website died.
Then I replaced the /ndxzsite/plugin (the whole folder) on my server by the original one in the indexhibit.zip upgrade.
My site went back on.
I tried again to replace the format.$format.php again.
The site died again!
Then I try to do one more time the trick of replacing the /ndxzsite/plugin folder on my server by the one in the original indexhibit.zip upgrade.
But it did not came back to life that time.
Please help me....
