Blank pages but not Memory_limit related
Anyone know of a cause for blank pages other than the memory_limit?
Trying to install a new copy of Tiki6.1. My memory limit is set to 512M, restarted Apache and verified with phpinfo(). I am running PHP 5.2.5 in localhost/tiki61 so modified .htaccess to set RedirectBase. Still blank.
Install ran fine up to last step where it attempts to redirect to a password update page, that page is blank. Tried localhost/tiki61/index.php and it rewrites to localhost/tiki61/tiki-index.php which is blank. Mysql has 233 tables and 6131 records loaded and all can be queried. My apache error log shows no errors. My access log shows the rewrite urls ok but NO indication of why all pages are blank.
I have a test copy of a much earlier tiki in localhost/tiki and it still works. Decided to upgrade to the latest version 6.1 and dump the demo junk before building the production tiki. So I believe the environment is good. Just lots and lots of empty pages.
-- update: when I posted this I had tried on my XP Pro. I started from scratch on a Windows 7 Pro (32-bit) where our ZendFramework sites are developed so all tools etc are up to date. Identical failure (64MB memory_limit).
