Refine Search widget from Classipress displays values of custom fields (checkboxes) which *cannot* be translated with WPML.
However the title (caption) of these custom fields *can* be translated. Please see screenshots attached.
To repro the issue on my site:
1. Goto http://www.immofirst.ch
2. Switch site language to French (or other language)
3. Click on Category button and select one category
4. Look at the Refine Search side bar expand some items
Is there any trick to get these fields translated? Some words still appear in English whereas they should be in French.
Let me know if more info is required. Any help is much appreciated.
