WP Super Cache and multiple domains

Hello All,

I am using two domains on my website, one for each language:
– website.fr in French (domain by default)
– website.uk in English

While using WP Super Cache, pages are cached correctly on both domains when a visitor access the page.

The issue is on the cache cleaning on the .uk domain:
– pages cached on the .uk don’t appear in the list of pages cached in Content, however they have been actually cached as I see it in the source code of the page
– pages cached on the .uk are not cleaned by the gabage collector
– if I manually delete all the pages cached, it doesn’t apply to the .uk domain

Going on without fixing this issue, the pages on the .uk domain will remain cached forever and never been refreshed.

Do you have any idea on how to use correctly WP Super Cache on all domains?

Thanks a lot!
