Just wanted to report that we are using Google Page Speed and the Upfront theme child themes (any of theme) are not compatible in it's current form. It also appears there is an error with Page Speed and Ultimate Branding as well.
Here is a sample of the errors:
[Mon May 11 15:17:18 2015] [warn] [mod_pagespeed 126.96.36.199-4448 @12883] CSS parsing error in http://ourwebsiteaddressgoeshere.com/?editmode=true
[Mon May 11 15:17:18 2015] [warn] [mod_pagespeed 188.8.131.52-4448 @12883] CSS parsing error in http://ourwebsiteaddressgoeshere.com/wp-content/plugins/ultimate-branding/ultimate-branding-files/modules/custom-admin-bar-files/css/general.css?ver=1.0
Can you let us know if you plan to support Google Page Speed with this theme and Ultimate Branding plugin?
We would prefer not to have to alter the CSS on each theme release in order for this to work, due to the nature of the Upfront theme and it's live editor, etc. Any suggestions are welcome. Thank you!
