Square WebPay support thread.

[carlwhat]

After uploading the files I get the following error in the log files:
PHP Fatal error: Uncaught Error: Class "Square\Environment" not found in MY_PATH/includes/modules/payment/square_webPay.php:105
Stack trace:
#0 /MY_PATH/modules.php(204): square_webPay->__construct()
#1 /: require('/home/tim/zenca...')
#2 {main}
thrown in /MY_PATH/includes/modules/payment/square_webPay.php on line 105

There appears no webpay module in Modules->Payment.

php Version is 8.0
Zen Cart 1.5.7d

you have not properly uploaded all the files in the zip. specifically the directory here:

/MY_PATH/includes/modules/payment/square_webPay/

there are a number of directories and more files there. those are all required.
