I don't know why it is ok now.
BTW, may I ask how to make the translated page have the same css style as default language page? As you can see I've only translated Home page from English and Traditional Chinese (TC). However, the heading and the background width of TC page showing different style from English page.
(Please let me know if I have to create a new post for this question.)
I'm sorry I just figured it out and didn't update here. So I have to go to dashboard, then go to "Home page", switch the dashboard(backend) to TC language, then choose the Astra settings from the right hand side.
Is there any faster way to do it like duplicate those settings from default language to the translate language?
If you go to edit the page, at the end you will find a block "Multilingual Content Setup".
The style of the page is defined by some theme custom fields, so in the custom fields section, you should set those to copy. This way, you will have the same settings regardless of the language.
These settings affect not only the page you are editing but all the pages. You can also edit them in WPML > Settings > Custom fields
If you want to have different styles per language: "copy once" or "translate" are the best options.
If you want to have the same style per language: "copy" is the best because it will keep the styles in synch. If you change it for one language, changes will apply for all.
Thanks for your help, but I think I need some time to figure it out. I feel comfortable as long as all warnings are cleared now.
BTW, please can you ask your development team to switch back the flag for Traditional Chinese. People like me are using both Simplified & Traditional Chinese got confused by looking at the flags. I have to wait a seconds to make sure I'm going to edit the right language.
