Before installing the new plugin, I updated all of my old plugins as well as WordPress to the latest version. I then installed WooCommerce DYMO Print from a zip file. I received a successful install message, but when I clicked on the activation link, I received the following error message:
Fatal error: Class 'WooThemes_Plugin_Updater' not found in /home/musecon/public_html/easy-macro.com/wp-content/plugins/woocommerce-export-csv/woocommerce-export-csv.php on line 37
I now cannot access my admin panel at all. Any known fixes?
