Update Breaks Child Functions.php

[icecast]

I cannot use child theme functions.php after updating to 1.62. I tried copying /themes/cardinal/functions.php to /themes/cardinal-child/functions.php but get white screen of death.

I made sure permissions and ownership were updated but did not change anything. Website pagespeed score drops 10 points with your default functions.php loading un-necessary scripts.

i believe issue may have to do with backend scripts in child functions.php

is it possible to have backend scripts in child functions.php?

Hi @icecast,

As I’ve said before, it’s not possible to load scripts based on the content, and so none of the scripts are “un-necessary”. They may not be of use to you, but that isn’t the same thing.

Check your error logs to see the cause of the white-screen. Backend scripts through a child theme should work fine.

i have an nginx server with only several plugins, and the google pagespeed score for mobile is in the low 50s. the mobile pagespeed score should be high 60s, low 70s. too many features with too many scripts can be counter-productive, that is why i submitted a feature request for a cardinal lite …

in functions.php, if i comment out woocommerce, flexslider, owl.carousel, ilightbox, and google maps, my mobile pagespeed score increases 10 points to low-mid 60s …

We run the standard, un-modified theme on http://cardinal.swiftideas.com, and get 77 for mobile speed without a CDN – https://www.dropbox.com/s/nhc6ryvndrpc88t/Screenshot%202014-08-26%2018.11.48.png?dl=0
