 * Hi!
 * 13.3.4 is the last version working without errors. Above that we receive the 
   following error.
 * Tried to deactivate / activate the plugin again, but it has failed with the same
   error:
 * [Tue Aug 27 18:59:45.335434 2024] [fcgid:warn] [pid 2856745:tid 2856749] [client]
   mod_fcgid: stderr: PHP Fatal error: Cannot declare class WooSEA_Activation, because
   the name is already in use in /home/www/clients/ /web/wp-content/plugins/woo-
   product-feed-pro/classes/class-activate.php on line 6, referer: /wp-admin/network/
   plugins.php?plugin=woo-product-feed-pro%2Fwoocommerce-sea.php

 * Hi [@eletsohu](https://wordpress.org/support/users/eletsohu/), this could only
   really happen if you have two copies activated. The activation class is only 
   used once.
 * Please check your /plugins folder for any misnamed directories that could be 
   duplicating the plugin. Our plugin folder should be exactly **woo-product-feed-
   pro**.
 * Alternatively, if you could post your WooCommerce Status info that would be a
   great help to debug this.

 * Hi! Thank you for your kind support.
 * I don’t have a duplicate plugin folder. Why would I? 🙂 
   I have a simple multisite
   environment.
 * The error first occured after 13.3.5.1 (2024-08-22)
 * I have noticed it when I was able to login to my main wp site, 
   but the subsite
   login failed with PHP fatal error.
 * I don’t want to be a smartass, but for me it seems, the issue originates from
   
   wp-content/plugins/woo-product-feed-pro/includes/Actions/Activation.php
 * WC Version: 9.1.4

 * We have this in hand and this issue will be fixed in the next release, thanks
   all!
