On the latest version of WordPress SEO (0.4.1) running a Network install - When visiting the export screen at /wp-admin/admin.php?page=wpseo_import and clicking the export button, I am present with an empty error below the field simply stating "Error: " but above the fieldset there is a PHP warning (see below). When I look in the plugin code, by searching the plugin folders contents for WPSEO_UPLOAD_DIR the definition is only referenced in the wpseo-non-ajax-functions.php file and I can't find where it is defined.
Warning: chdir() [function.chdir]: No such file or directory (errno 2) in /html/wp-content/plugins/wordpress-seo/inc/wpseo-non-ajax-functions.php on line 93
Should I export from the database instead? Thanks
