I’ve got a Ren’Py novel(-ette). I’ve made a Web build. I zipped the files that came out and uploaded the zip to itch.io. I clicked “This game will be playable in the browser.” I saved.

When I click View page—> Play, I get “All downloads complete. Warning: cannot save games” and an endlessly spinning buffer thingy.

If I click the hamburger in the upper left (Import saves; Export saves; Ren’Py log), selecting Ren’Py log tells me "Error opening /log.txt" I don't see a log.txt in my pre-zipped files. Where does this file come from? Or is there another problem elsewhere?

Ren'Py 7.4.8.1985 for Mac OS

Thank you!
