Background of the issue:
I am trying to translate a product template from Italian to German using WPML.
Symptoms:
Some templates can't translate to other languages, leaving a critical error. This issue doesn't happen for all products, only some. I expected to see the translation editor, but instead, I got an error screen.
Questions:
Why does translating some product templates result in a critical error?
Why does this issue occur only for some products and not all?
Moreover, there are some queues that don't progress, why? please see screenshot.
1.- Please share the fatal error message in your next reply so we can get more information on the issue.
2.- I kindly ask you to describe step-by-step how to reproduce the issue on the site, because you mentioned templates and products, and I'm not sure what you are referring to.
Hi Moreno,
Thank you very much for sharing the video
1.- I kindly ask you to follow these steps:
- Create a full site backup
- Activate the WordPress debug mode as described in this guide: https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/
- Reproduce the error
- Share the latest fatal error that appears in the debug.log file located within the wp-content folder
2.- Also, have you noticed if there is something in common between the templates and/or the products where the error appears?
