Tips and notes

• Enable WordPress debug mode (WP_DEBUG) to see detailed error messages
• Deactivate all plugins to check if a plugin conflict is causing the error
• Switch to a default theme (like Twenty Twenty-Four) to rule out theme issues
• Always keep a recent backup so you can restore your site if needed
