I have purchased the theme few days ago and since I have tried to set it up and I am encountering a lot of problems. The demo import of the theme does not work and when I inspect the code, it tells me that there was an 500 error refering to admin-ajax.php file.
I have setup the environment and I have done all the indications given through the documentation.
I also tried to do it manually but the footers and the headers of the theme are not working correctly as I cannot import the file widget_data.json (the plugin required to import it is no longer available and as the extension is .json and not .wie it does not work on most of the widget importer on wordpress)
