Working this problem still– I’m trying a new install instead of the upgrade and am now getting this error repeatedly:
Warning: preg_match() [function.preg-match]: Internal pcre_fullinfo() error -3 in /home/mysite/htdocs/wordpress/wp-includes/vars.php on line 18
It crashes on the email validation for a new install– it says my good email address in invalid.
This is not an actual WordPress bug, it’s a PHP configuration or installation issue.
This sort of error generally happens when you have incompatible versions of PHP and the PCRE library. You may want to examine your PHP installation closer.
Thanks Otto42, you’re right. My PCRE library was out of date. So the preg_match error is cleaned up, but I’m back to still just getting a blank page. Everything else looks good on my PHP installation.
I got a white screen of death, too — try renaming your plugins folder and see if your site shows back up. If so, it’s a plugin causing the problem.
OK I **SUCCESSFULLY** installed:
WordPress 2.1.2
PHP 5.2.1
MySQL 5.0.37
on a Windows 2003 platform
(once in IIS 6.0 and a 2nd install in APACHE 2.2.4
However although WordPress appears to run fine I can’t get plugins to work properly.
I BELIEVE IT IS AN ISSUE WITH PHP5 VS PHP4 INCOMPATIBILITIES (because the plugins do work on a seperate PHP4 server fine).
Well its back to the drawing board, time to uninstall APACHE\IIS, MYSQL, PHP5, TOMCAT, and PHPMyAdmin and then install PHP4 to test my theory…. 🙁
