Almost a year now and still have the same problem.Back then I stopped using Perth pro because I couldn’t import the custom post type settings, and to be honest I completely forgot it until two days ago started using theme again and was facing the same problem. Suddenly it hit me, that almost a year ago I was where I’m now, unable to import the custom post type (perth settings).
Maybe back then I wasn’t precise enough, but the issue is that when I go to import via Toolset to import the settings, the upload button seems already pressed down. Normally before clicking the button looks fully colored and after pressing, it looks faded. In my case, the upload button looks constantly pressed/faded, like it already has been pressed.
I have also tried to copy and paste the entire XML file and didn’t work either, because of the same reason.
I have recently uninstalled and installed all the plugins, even theme and it still the same.
I’m thinking that maybe I can upload it via FTP? any other suggestions?
