While everything's normal in Framer Studio, I get this when I opened the generated "index.html". Any clues? I am using version 1.8.17
Looks like your plugin "Huaban Collector" is messing stuff up. Disable extensions and try again. Also, you should run it from a server if you look in Chrome. Read that error link or use the Mirror feature.
I tried disabling extensions and I did run it from a sever but it didn't work. I also tried Safari but got the same problem.
