Wordpress in subdirectory error

[Hani]

I have a Wordpress blog installed in a subdirectory of a PW site (transferring the blog from WP to PW is on my task list) that was working with Processwire 2.2.9.  I just upgraded to 2.4 and it broke.  

The error I'm getting is:

Fatal error: Cannot redeclare __() (previously declared in /home/me/mydomain.com/blog/wp-includes/l10n.php:146) in /home/me/mydomain.com/wire/core/LanguageFunctions.php on line 39

Any idea what I can do (temporarily) to get it up and running?

Processwire is installed at the root of the domain and Wordpress is installed at /blog.

EDIT: I don't have any of the Language Support modules installed.

Now that I think about it, shouldn't the .htaccess file not even give Processwire "control" since the /blog/ directory physically exists on the server?

This line in the .htaccess file should take care of that, right?

RewriteCond %{REQUEST_FILENAME} !-d

For anyone else who runs into this issue, a quick, temporary fix is to hack the LanguageFunctions.php file.  For all three functions in there, you'll need to wrap each with a check to make sure the functions haven't already been declared.  For example, the first function:

if (!function_exists ('__')){
    function __($text, $textdomain = null, $context = '') {
            ...snip...
    }
}

My best guess is that this not recommended as a permanent solution since it may cause issues with WordPress.  And of course, ProcessWire upgrades will overwrite the hack.

Best solution? Don't use Wordpress.
