What are common pitfalls when installing PHP applications like phpmychat?

One common pitfall when installing PHP applications like phpmychat is not setting the correct file permissions for directories and files. This can lead to errors when trying to access or modify files within the application. To solve this issue, make sure to set the appropriate file permissions for directories (usually 755) and files (usually 644) using chmod command in the terminal.

// Set correct file permissions for directories and files
// Directories: 755, Files: 644
chmod("/path/to/directory", 0755);
chmod("/path/to/file", 0644);
