So I managed to fix it by changing both SiteURL and homeURL to being the exact same. Now I’ve finally added an A-record in my DNS so the sites uses its own URL. Works like a charm 🙂
Im not sure why but I’ve seen others place “http://…” for SiteURL and “http://www…” for homeURL. However, this wouldn’t work in my case even. Hope it can help other who face the same problem.
