I get an error when visiting the collection detail page. I’ve seen similar threads where people have solved it by switching on the “Publish this Collection Template page”, the toggle switch in settings of the corresponding Collection Page, but this is not fixing the issue for me.
Are there any other solutions for this problem, or different stuff I am overlooking here?
I also just realised the following: two of the four links are working, so when on the live (staging) site the first two redirects to the project result in 404, the two last items are in fact redirecting correctly to the CMS collection page (with the according project content)
I inspected the url for each item to see if there is something odd there, but there seems no faults in the urls.
Finally decided to update the Collection URL in CMS Collections settings, and this seemed to solve the issue. Not quite sure why, but it did …
Sounds like you have some 301 redirects in your site settings that are conflicting with the setup you’re wanting. Changing the collection slug would mean a different path and would sidestep those redirects.
