Symptoms:
I can't save the settings for each language so that the PDF generates information in different languages. The English page is always used in the PDF, and the button cannot be translated because the page settings are not saved, only one language is saved.
Questions:
Why can't I save the settings for each language in WooCommerce PDF Invoices?
How can I ensure that the PDF generates information in different languages using WPML?
Why is the English page always used in the PDF despite different language settings?
How can I translate the button if the page settings are not saved?
thanks for the patience and sorry for the long wait.
I have checked and was able to reproduce this issue on a clean test site, it seems to be a compatibility bug with WPML and WooCommerce PDF Invoices by Andrew Benbow plugin.
Please note this plugin is not officially compatible with WPML nor was tested by us, we will try to help but in the end, it might need author collaboration to continue further and them joining our GoGLobal compatibility program. https://wpml.org/documentation/support/go-global-program/
