I tried exporting and importing the settings of mariannalanteri.com to mariannalanteri.it but nothing happens. I have tried all the import and export methods.

Update:

I put the settings manually and now the audio player works, I ha put a redirect from the .com to the .it, probably there was conflict with the theme. For now, problems have been solved, even though I didn't understand why the import and export of theme settings didn't work
