@ryanstraight, could I please see your config file also? Did you try to set up cache busting of assets?

[chrisarusso]

FWIW @ryanstraight when I updated the two lines from the included config.toml

from

# Cache busting of static resources (additional set up required)
cacheBustCSS = true
cacheBustJS = true

to

# Cache busting of static resources (additional set up required)
cacheBustCSS = false
cacheBustJS = false

the site loaded for me. I did not set up cachebusting initially, so it should probably work for you too if you hadn't set it up.

[tomanistor]

That's likely the issue.

That cache-busting feature was added to the theme before Hugo Asset Pipelines were released with Hugo v0.43. One of my goals is to update this theme to use the Hugo Asset Pipelines instead of
relying on users of the theme manually setting up cache-busting, which would prevent errors like this.
