Square WebPay support thread.

[todoonada]

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.

I uploaded all files, so missing files were not the problem.
I found the reason why I can not see the WebPay module and get aforementioned error:
When I am on PHP-version 8.0.17 I get an error.
Switching to PHP 7.4.28, I do not get an error and the module shows up.
