I'm moving a dev site to production and i've notice a huge number of errors being created. These are in the dev server and the production server. They all are like this and seem to apply to one line in a css.php file. I've pasted the larger section of the error log in the hidden content but for anyone else who pay search for this a shortened line is included below.
Attempt to read property "xs" on null in /var/www/xxxxxxxx/components/com_sppagebuilder/layouts/row/css.php on line 585
I'm using Spagebuilder Version 4.0.10. These errors are too many to ignore in a log file.
