Are there any common pitfalls or errors that users may encounter when following Symphony installation instructions?

One common pitfall users may encounter when following Symphony installation instructions is forgetting to set the correct permissions for certain directories or files, leading to errors related to file access. To solve this issue, users should ensure that the appropriate directories have the correct permissions set, typically 755 for directories and 644 for files.

// Set permissions for directories
chmod('/path/to/directory', 0755);

// Set permissions for files
chmod('/path/to/file', 0644);
