Hi there,
for a friend I tried to update to indexhibit version two. I followed the tutorial, but got a couple of "string index out of range" warnings and the import didn't quite work.
I traced the error down to line 1045 in install.php and there you have: $page = '';
As $page is supposed to be an aray, i think this causes the error.
I changed that line to:
$page = array();
And then tried again. For me it worked.
But take this with a grain of salt. I did no extensive testing on this issue. But I thought this might help.
Best wishes,
Frank Christian Stoffel
