Updating to OS X 10.10.2 broke Quick Look previews for HTML files After updating to OS X 10.10.2, I can no longer use Quick Look on HTML files – I just get a blank preview window, and the issue persists through a reboot. But all other files types work fine.

Is there a cache I can clear or something else I can try to get this working again?

10.10.2 quick look broken for HTML files

qlmanage -t &lt;path_to_html_file&gt; produces a small thumbnail of the HMTL file
qlmanage -p &lt;path_to_html_file&gt; just gives me a blank quicklook preview

This doesn't happen with a .jpg file I used as a control sample.
