For the product to be in the URL you must edit your cpt settings and change the slug to products. The moving-lights taxonomy is this from the default wordpress category ?
I just wanted to add that I've tried switching to the Twenty Nineteen theme to rule out any theme issues and it's not made any difference so I've switched it back.
Mind If I gained access to check on the structures ?
This might be possible but I can't make any promises that this can work because you've defined your CPT slug as dpl-product. The only way to get that to be just 'product' is by changing the slug itself.
The Post Type can have the slug "product" but not "products" as you have it because there will be a conflict with the URL's for the Category and the CPT.
The reason for this is that in the settings -> permalinks i see that you category taxonomy slug is "products". I went ahead and changed your CPT slug to "product" so there should be some similarities now.
Many thanks for that. I'm afraid this hasn't addressed the issue.
The problem isn't the actual slug, it's the fact that there is the taxonomy hierarchy in the URL for the archive pages but it's completely lost when you go to the single page.
This is an archive page: hidden link
It has products...moving-lights...spot in the breadcrumbs.
This is one of the single pages from that archive: hidden link
It loses the products...moving-lights...spot and just has product.
I need the single page to have this URL structure: hidden link
It also, of course, affects the breadcrumbs (taken from the Yoast plugin) which needs to be consistent.
Actually, I think we can close this. I've spotted it's a WordPress issue (and possible Yoast) which is causing this. I've made some tweaks to the settings and the breadcrumbs are now much better and, probably, as good as I can get them.
Thanks again for your time, I really do appreciate it. I'll close this thread and come back to you if I hit any further issues.
