I have problems with some themes that introduce custom post types as homepage elements, like sliders, portfolios and features/homeboxes. Polylang recognizes the custom post types introduced by the themes and some of them are translatable and work correctly but others, even if I check the corresponding checkboxes in Polylang Settings page, are either not translatable or don't 'keep' the translations (the last translation overwrite the previous ones). I use WP 3.5.1 and Polylang 1.0.1 in a test localhost environment.
The (free) themes are:
- Sitecorp and Boldy by Site5: they both add three custom post types (CPT), Portfolio, Slider and Options Framework Internal Container, and one custom taxonomy (CT), Types. If I switch theme and then switch back only Portfolio stay checked while the others need to be checked.
Portfolio is partially translatable, which means that title and content fields can be different as per language but the media (e.g. image) field is not. Slider is not translatable which means that the 'widget' that allows to selct language and add/edit corresponding translations doesn't show up, and none of its fields (title, caption, image link and image) can be translated. Options Framework Internal Container is not translatable but this is different from Slider because you can set values for this custom post type only through Theme Options->Homepage, it doesn't exist on the dashboard a tab (like Pages, Posts, etc.) that allows to add/edit/delete the posts.
- Swatch by Woothemes: it adds five CPTs, WooFramework Internal Container, Mini-Features, Slides, Portfolio and Feedback, and one CT, Portfolio Galleries. If I switch theme all but the CT stay checked.
Slides, Portfolio and Mini-features are partially translatable, title and content can be different as per language but all the other fields, that are in the Swatch Custom Settings pane, are not translatable. I haven't tried Feedbacks but I suspect that they have the same problem. One thing that i noticed is that on Slides and Portfolio lists there aren't flags and plus/pensil symbols on the right side of the windowpane, while Mini-features and Feedback lists have the flags and plus/pencil symbols on the right.
- Panoramica by CPOThemes: it adds three CPTs, Slides, Features and Portfolio and one CT, Categories. This is the theme that works best with Polylang because all the CPTs and and almost all of their fields are translatable. Maybe I have not tried everything yet but so far only the images, that are set as featured images, aren't translatable (this would be important only if I'd need to show different images for different languages, which is not my case). All the CPTs lists show flags and plus/pensil symbols on the right side of the windowpane.
Thanks a lot for your help!
