Dear All,
If your site are using both extensions: Ecomteck_OneStepCheckout and MageWorx_MultiFees extensions and get error on checkout page (the loading spinner still not done, or payment fees, shipping fees not apply)
Please setup the extension: https://github.com/ecomteck/module-one-step-checkout-compatible
Setup it with composer as steps:
composer require ecomteck/module-one-step-checkout-compatible php bin/magento setup:upgrade php bin/magento setup:static-content:deploy -f php bin/magento cache:clean
Or download module file:
https://github.com/ecomteck/module-one-step-checkout-compatible/releases
And run commands:
php bin/magento setup:upgrade php bin/magento setup:static-content:deploy -f php bin/magento cache:clean
Go to admin to create new transactional email template.
On the email template content area add the variable shortcode as this:
{{var order.getEcomteckOrderComment()}}
