An unknown error occurred while discovering dynamically related files.
I do not understand this issue. It was working fine yesterday.
I am not using wordpress. This is a custom PHP file which takes information from an ftp server and updates my SQL database. It is running on my computer. I am using Apache Server 2.0 with macOS Server. In addition, the console reads this:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /ftpaddress.php.
Reason: Error reading from remote server
I try to rerun the program and I see "An unknown error occurred while discovering dynamically related files. Retry" Could this be an internet connection issue? Or could I have damaged my code?
