I created a droplet server in DigitalOcean and set the DNS. Let's say domain is example.com. I deployed React project to domain first. When I enter the domain in chrome browser, it redirects example.com/login. Now I replaced it with PHP project. (they are different and independent projects) But domain shows me old website mostly, and rarely it shows me updated one. What is the problem, and how can I fix it? Thank you.
As I mentioned above, I replaced old project with new one, but domain on browser shows me old one mostly. Rarely it shows me new one updated. It's related to DNS cache? But it's already been three days.
