According to this thread (https://theme.co/apex/forums/topic/incorrect-path-to-ilightbox-ajax-loading-gif/) it is known that some elements are not being addressed correctly in the CSS.
I am running W3 Cache - checking for broken links after turning on W3s minify process, these are the ones we are missing:
The first two are clearly wrong because of the repeated “framework”
The 3rd location only contains css files
I am unsure how I should address the corrections in the custom CSS.
