You might find an error with
your-domin.com/socket.io.min.js
-One way to fix it is-
1. Move socket.io.min.js from the plugin folder into something like Dropbox.
2. Change the dependency line in edittime.js
Note: If you have multiple socket.io plugins one may override the other. Replacing the dependency of both may work but I just deleted the other plugin.
3. Change the link in runtime.js inside document.write() [line 2] to hte same link you pasted previously.
Edit: During a compile you may get an error regarding a missing dependency since the project is essentially compiling without it. Just click retry and it shouldn't pop up again until the next time you open the project.
