Hello, the error log is within:
- enable "log checkout errors" in general tab
- visit frontend which should install Facebook SDK at first visit
- see the OPC Error log section (in opc menu at BE at left side)
The system uses modified composer for web installation of 3rd party libraries into /libraries folder. In recent OPC i adjusted the installer to use always "current php version" as directory path, so that one library can be used with php7.4 and another one with php8.1. Generally companies like Stripe or Facebook require to use non-EOL version of PHP and thus it is possible that Facebook SDK requires at least php8.1
OPC's facebook's tracking tries to install:
https://github.com/facebook/facebook-ph ... s/main.zipinto:
/libraries/vendor/facebook-php-business-sdk/'.PHP_MAJOR_VERSION.'.'.PHP_MINOR_VERSION.'/'
Facebook's SDK page is at
https://github.com/facebook/facebook-php-business-sdkyou might want to extract and install it manually, so that composer.json is in:
/libraries/vendor/facebook-php-business-sdk/8.2/facebook-php-business-sdk-main/composer.json
and autoload in:
/libraries/vendor/facebook-php-business-sdk/8.2/facebook-php-business-sdk-main/vendor/autoload.php
best regards, stan
