If you’re affected by the bug in Realteo 1.0.5 that displays 4* “array” instead of Offer Types, here’s how to fix it.
Make sure you have the latest version of Findeo theme and plugins installed (you can check it in Appearance -> Install Plugins – if you don’t have it in menu it means everything is updated, if you do see it, you can update plugins from that page)

This problem should be gone after updating plugins, but might still be there if you’ve used Realteo Editor to edit fields or search forms. In that case go to Realteo Editor > Fields -> and in Offer Type field you should have empty Predefined list

Select from that dropdown Offer Types List and save
Do the same thing for all Offer Type field in Search forms editors
