PhastPress and nginx

Hi there,

First of all, thank you for this fantastic plugin!

I recently migrated my WordPress site from an Apache server to a new server running Nginx. Everything was working perfectly, including PhastPress, until I manually deleted the /wp-content/cache/phastpress.* folders.

Since then, reactivating PhastPress does not recreate the phastpress.* folders in the /wp-content/cache/ directory. It still modifies the image URLs as expected, but the image URL returns a 404 error.

Could this be related to a permission issue with Nginx? Is there something specific I need to configure to allow PhastPress to recreate the cache directories under Nginx?

Also, I have tried to recreate this .htaccess logic…

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^wp-content/.*[^/].(jpe?g|gif|png)$ wp-content/plugins/phastpress/phast.php [L,NC,E=PHAST_SERVICE:images]

…in Nginx, but it did not work:

location ~* ^/wp-content/.*\.(jpe?g|png|gif)$ {
    root /home/kaffeeart.eu/public_html;

    if (-f $request_filename) {
        set $phast_service "images";
        rewrite ^/wp-content/.*\.(jpe?g|png|gif)$ /wp-content/plugins/phastpress/phast.php last;
    }
}

Thanks in advance for your help!
