[TYPO3-linux] Blank page after step 3 of 1-2-3 install

[M. Stanley]

I'm trying to set up TYPO3 3.8.1 and after step 3 of the 1-2-3 install tool 
I get a blank page...

I've set the amount of memory PHP scripts are allowed to use from the 
default 8MB to 64M but that didn't fix the problem.

My PHP error log says the following:
PHP Fatal error:  Allowed memory size of 8388608 bytes exhausted (tried to 
allocate 3377 bytes) in 
/var/www/typo3_src-3.8.1/t3lib/class.t3lib_install.php on line 596

What is wrong and how do I fix it???
