Hi store owners, just making you aware that there is a Plugin compatibility issue with Store Exporter and the new WordPress 3.9.1. If error reporting is turned on for your hosting account a PHP warning may appear at the top of your WordPress Administration pages looking like this.

Warning: Missing argument 2 for …_ce_add_missing_mime_type() in …/wp-content/plugins/woocommerce-exporter/includes/functions.php on line 877

Warning: Cannot modify header information – headers already sent by (output started at …/wp-content/plugins/woocommerce-exporter/includes/functions.php:877) in …/wp-content/plugins/woocommerce-exporter/includes/functions.php on line 155

We will be releasing a minor Plugin update later today to resolve this issue. Thank you for your patience.
