Overview of the issue
When you complete the translations for posts or pages created by Oxygen Builder, the translations do not display on the front-end.
Workaround
Oxygen Builder is not currently compatible with WPML. The only option for translating pages built with Oxygen Builder is to translate them manually. We’re working with the Oxygen Builder development team to fix this issue.
If this doesn’t help, please open a chat in our technical support.
