I’m using a PHP CMS program that works perfectly on one of my VPS instances (running Centmin Mod 123.09beta01). However, after migrating the program to a new VPS with a fresh installation of Centmin Mod 131stable, the multi-photo upload function stopped working, and no pictures can be uploaded. The error message simply says, "Upload failed."

I’ve checked the file permissions, and the owner/group are correctly set to nginx:nginx. The script has also been tested locally and works without any issues.

I’ve been troubleshooting this for several weeks now but haven’t been able to identify the root cause. Since the script works on the older VPS and locally, I suspect the problem might be related to the current server’s configuration. Could you provide any guidance to help me resolve this issue?

Just to let you know, the problem has been resolved. It turned out to be a small mistake that isn’t acceptable in newer PHP versions.
