I can open the same PHP file from a different server (Server 9) without any issues. At first, I thought there was an error in the PHP file itself, but it turns out the problem isn’t in the file—that’s why I’m writing about it; otherwise, I wouldn’t have bothered. I tried changing the PHP version randomly, but let me explain it like this: my PHP file, which was working on Server 7 yesterday and is currently working fine on a different hosting provider, isn’t working on Server 7 today. There’s no error in the code itself—I can access it without any problems from the same address through a different hosting provider right now, but it’s throwing an error on Server 7.
