@WebElaine sorry I pulled that from a working site, yeah option is defined I have edited the function accordingly. The function does work and changes the sites url as per the logic, but they return 404s
@WebElaine I have edited the question to include what I did try and didn't work. Kind of works on the same logic but it didnt work. (apologies I should have included it in the original post)
@JacobPeattie Apologies, I had a feeling that might be an issue. Unfortunately they appear to have closed their support forum and there isn't any presence on wordpress.org. StackExchange was my next bet.
