I get the error on my client site [exporting the code from webflow].
It works fine in webflow´s server and works fine deploying to my own server,
but the javascript seems broken when the client deploys the code in their server.
“SyntaxError: identifier starts immediately after numeric literal (Firefox)”
“SyntaxError: Unexpected number (Chrome)”
You said that it deploys fine to your own server, and I’m assuming that’s an external one as well.
It sounds like the client is doing something to modify the script, could be a bad minification process or something else at deployment.
I’d check their process, and their server settings to see what’s modifying webflow.js.
