Hi Ron,
thank you for your reply.
I believe that I still need domain mapping because the WP Multi install will use 2 different domain names with 2 versions each:
mydomain.be/fr
mydomain.be/en
anotherdomain.be/fr
anotherdomain.be/en
For now, the best solution I tested is to use domain mapping but with subdomain instead of folders so ending up with URLs like:
fr.mydomain.be/
en.mydomain.be/
fr.anotherdomain.be/
en.anotherdomain.be/
Also, I am using WP Multi with subdomain, not with folders.
Do you have any other tips on this issue ?
Thank you :^)
