I’ve inserted the code into the parent theme’s header-functions.php instead of the child’s and it works now ;)
For the record, in total during the setup of the Infinite Scroll I’ve made changes to the following files:
– added folder /infinitescroll/ to the parent theme’s /scripts/ folder
– modified parent’s “functions.php”
– modified parent’s “header-functions.php”
– modified child’s “page_portfolio.php”
Important notice: the plugin does not take into account sticky posts in its architecture, thus in case you have sticky posts, they will keep re-appearing at the very bottom of the page once you scroll all the way down; it is therefore advised not to have sticky portfolio projects while the plugin is active.
Sincerely,
Andrew / Satori Studio
