TOPIC:

We've done more testing. I was using XOT and unzipping the file. There seems to be an issue with some modern browsers, in that the exported files seem to contain something which is trying to call local files, you therefore get a CORS or script undefined error (visible from the browsers console), in Chrome it's stating that you must use only recognised protocols, 'file' being the one disallowed.

This has been tried on:

MAC OSX (10.11) Safari - Works
MAC OSX (10.11) Chrome - Fails with XMLHttpRequest CORS error
MAC OSX (10.11) FireFox - Works

Windows 10 Chrome - Fails with XMLHttpRequest CORS error
Windows 10 FireFox - Works
Windows 10 IE 11 - Fails with $script is undefined
Windows 10 IE Edge - Fails with $script is undefined

We've tried running Chrome with the option --allow-file-access-from-files, and this seems to enable it to work.

Sorry meant to add this is Xerte 3.3 and was the offline zip.

Can you share a link to a zip that isn't working for you? (won't attach here so you'll need to upload somewhere first e.g. Dropbox, Google drive etc)
Here's a link to a simple two page offline export: dl.dropboxusercontent.com/u/1388941/Test_file_offline.zip

Haven't tested on Mac but on Windows opens fine in Chrome, Firefox, Opera and in IE and Edge opens fine too but prompts to allow blocked content.
