First of all, thank you for this wonderful tool, we moved from WPML and Polylang is a better fit for what we do.
We have a website with network capabilities enabled, and the polylang (1.5) plugin installed globally on the network. We have multiple websites, each with multiple languages.
Our WordPress (3.9.1) is installed in a subfolder, and the project files (themes, plugins, uploads) are in an "app/" folder at root. The wp-config.php file is updated to reflect this structure.
The problem appears when we try to use the "The language is set from different domains" option (in the Settings pane of polylang) : We have multiple domains, let's say domain1.com and domain2.com. The blog domain is set as "domain1.com" and its path is "/". Then, in the polylang configuration, we specified that "domain2.com" would be the english version of the site. The default site is on "defaultdomain.com".
When we try to reach "domain2.com" (english version of a site), we are redirected to the network default site, defaultdomain.com.
Is it something you already heard about ? How can we solve this ? I haven't found recent information adressing this issue, but if you have indications, maybe we can get our hands dirty with the code and try to get more information.
