PHP error Undefined Array key

Hi Repon,

First off I would like to thank you for all the great support you’ve provided.

We are still running into an issue though.
Today, we see 500 errors occur when we visit the site.

On inspecting the error logs, I can only find one single error. The error is related to an undefined array key in the class-popup.php file.

Could you provide us with a fix, please?

[Thu May 02 09:49:13.680900 2024] [error] [pid 2845205] mod_proxy_fcgi.c(902): [client xxx.xxx.xxx.xxx:0] AH01071: Got error ‘PHP message: PHP Warning: Undefined array key “” in /wp-content/plugins/freight-shipping-quote/inc/class-popup.php on line 139’

I’ve added an example of the PHP error. The error is occuring every few seconds when someone visits the site.

Thanks again,
Joel
