Enhanced error reporting: - Show detailed diagnostic information: git version, user config, email, remote, branch - Check .git directory and config file existence - Detect if repository has uncommitted changes - Error categorization: PERMISSION, CONFIG, REPO, NETWORK, SSL, GIT errors - Actionable error messages with command suggestions - Report raw error output to log file for debugging Added setup_git_config.sh script: - Automated configuration for www-data user - Creates .ssh directory with proper permissions - Sets git user.name and user.email globally - Disables SSL verification (for HTTPS repos) - Configures git to use HTTPS remote URL - Fixes directory ownership and permissions - Tests git status to verify configuration Usage on live server: sudo bash setup_git_config.sh This script handles the common git configuration issues that prevent 'Update HMS' button from working.
