I'm running into an unusual error when I try to move the master password web files to a live web server. I always get this error in Chrome:
Uncaught ReferenceError: CryptoJS is not defined
    at pbkdf2.js:117
    at scrypt.js?1:127
    at Function.calculateKey (mpw.js?1:76)
    at new MPW (mpw.js?1:19)
    at updateMPW (main.js?3:6)

This is true using both the most current version of the MPW javascript code ( from, and using exact copies of the javascript saved from the live site ( I do not get this error on any other browser (firefox and safari on iOS).

Interestingly I don't get it in chrome either if I go to the local index.html on my computer. Is there some setting I am forgetting to enable on the web server?

    Seems to work just fine when I try it out in Chrome. What are your browser specifics?

    Mine are:
    Version 67.0.3396.99 (Official Build) (64-bit)
    macOS 10.13.6 (17G65)

    Mine is Version 68.0.3440.84 (Official Build) (64-bit)
    System is Windows 10.

    Interestingly this only happens on a live web server. I can go to the files hosted locally in a random directory and it will work fine.

    I think I figured out the problem.
    It was the fact that the attached block was commented out, and my site does not have https so chrome makes window.crypto.subtle undefined (while the CryptoJS stuff isn't being imported). I uncommented the section and it didn't work in my case because the javascript code was being taken from the browser cache. I ended up moving the commented section to a script tag on the main index.html page to solve the issue. I'm pretty sure adding a randomized parameter to the script import calls using PHP would force the browser to always pull fresh javascript from the server.
