We're running W3TC with WPML and have domain per language option running.
On the 'default' domain, W3TC works great, however, on the other language domains it gives us a 'hostname mistmatch' in the debug output of the page cache, and obvious no page cache is working on the translation domains.
Is there an option we didn't find, or a patch to get W3TC tunning for the domains configured in WPML as language domains, or configure the allowed domains in a config file?
The WPML setup is:
The content of these site are translated and handled by WPML nicely.
We are running W3TC 9.2.5.
Thanks for any help and/or input in this.
