Ok, I figured I'd give it a go at installing 7.0 and then upgrading from 6.5.5

I go thru the install with pretty much no issues and then run through thread_import.php just fine, except as soon as it finishes and give me the link to go ahead and log into my newly setup/imported 7.0, I click the link and get a "PHP has encountered a Stack overflow" error trying to load "/ubbthreads.php?ubb=login".

Running Win2k3 SP1, IIS6 (isapi), MySQL - 4.0.26-nt, PHP 4.4.4 (php4isapi.dll).

Download of 7.0 was today.
Imported from a fully functioning 6.5.5 site.

What little I can find on that error hints at Zend Optimizer, but I don't even have that installed.

Any help would be greatly appreciated...thanks in advance.

Jesus was an architect previous to his career as a prophet
All of a sudden, I found myself in love with the world
So there was only one thing that I could do
Was ding a ding dang my dang a long ling long
