When I try to install, a pop-up fatal error occurs. How to fix this issue?

Are you getting the Fatal error message when installing the WooCommerce FedEx Shipping Plugin with Print Label? This article should help you solve the error. Read below.


When I try to install the plugin, I receive pop-up showing fatal error, as shown below:

Fatal error: Cannot redeclare wf_fedex_activation_check() (previously declared in/home/baymed2578/public_html/wp-content/plugins/fedex-woocommerce-shipping-method/fedexwoocommerce-shipping.php:17) in /home/baymed2578/public_html/wpcontent/plugins/fedex-woocommerce-shipping/fedex-woocommerce-shipping.php on line 21

Please help.

PluginHive Support:

We suggest you to delete the basic version of the plugin and then install the premium version.


I was following your instruction and seems like it works, but after I got test number from FedEx, appeared another error –

Warning: Invalid argument supplied for for each() in /home/baymed2578/public_html/wpcontent/plugins/FedEx-woocommerce-shipping/includes/classwf-fedex-woocommerce-shipping.php on line 473

Could you help me with the above error?

For your additional information, I didn’t see any shipping choices for FedEx (such as FedEx ground etc) on check out page and shopping cart page.
