Hooray! Following renewed calls for HTTPS support on MODX.com, the team has made the necessary changes, and as of today you will browse the website securely.

If you find any issues browsing the MODX.com website or subdomains over HTTPS, please let the team know via help@modx.com or on Slack. Not all mixed content warnings are easily fixed on the current website due to 10 years of legacy, but with a new site on the way those issues should be temporary. 

Inspired to also run your MODX site on HTTPS? Let's Encrypt can provide you a free certificate, and MODX itself can run over SSL without any extras.
