I can't preview my Wix Code site, not in Safari and not in Chrome.
I am able to preview successfully in Chrome and IE. Not sure about Safari, yet.
I was having some issues with the editor, ended up restoring my site to a previous save and that worked.
Seem to be site dependant. Where I don't have Data Collections I can preview but where I have a lot of Data Collection it works just the first time then everything stops.
Can you please share a link to your site/editor?
