Your PHP installation appears to be missing the MySQL which is required for WP

I am setting up my first dedicated box.

1. Windows 2003,
2. IIS6,
3. PHP 5.2 build 3790
4. MySQL5.

I had my host install PHP for me.

I installed MySQL and got it working fine with my Coldfusion pages - so we know the database is work.

I created a PHP hello world page and it worked fine. So we know PHP is working.

But when I tried my WordPress blog I get:

“Your PHP installation appears to be missing the MySQL which is required for WordPress.”

So I Google the error and found this helpful page:

I added both IUSR_COMPUTERNAME and “Network Service” to have
read/write access to C:\PHP like they talked about - but that didn’t work.

I made sure that the php_mysql.dll extension was uncommented (restarted IIS) - but that didn’t work.

In php.ini file, I changed the “extension_dir” to point to “./ext/” (restarted IIS) - but that didn’t work.

I then tried “extension_dir” to point to “C:\PHP\ext\” (restarted IIS) - but that didn’t work.

I then tried “extension_dir” to point to “C:\PHP\” (restarted IIS) - but that didn’t work.

Here is the php info for MySQL:

Update: I figured it out. All the settings above are correct. For some reason I just needed to reinstall Wordpress.

Update 2: I didn’t have to reinstall WP, all I had to do was deactivate one of my plugins (Quick Stats which was causing the error).
