Troubleshooting Blogus Dark Mode: Why Your Preference Doesn't Save Between Pages

17 threads Sep 16, 2025 Theme → Blogus

Content

Many Blogus theme users have encountered a frustrating issue with the dark mode toggle: while it works perfectly on the current page, the preference doesn't persist when navigating to other pages. This guide explains why this happens and provides potential solutions.

The Problem: Session-Based Dark Mode

Based on user reports and analysis, the dark mode toggle in the Blogus theme demo appears to function as a session-based feature rather than a persistent user preference. The theme uses localStorage.setItem() to store the preference, but this implementation only maintains the setting during the current browsing session or until page refresh.

Why This Happens

The Blogus team has indicated this is the intended functionality for their live demo switcher. The light/dark mode toggle is designed as a preview feature that persists until page reload or navigation, rather than a permanent user setting that would be saved across the entire browsing experience.

Potential Solutions

1. Check Theme Documentation

First, consult the official Blogus theme documentation for any built-in dark mode persistence settings. Some themes include configuration options that need to be enabled for full functionality.

2. Custom JavaScript Implementation

For developers comfortable with code modifications, you can enhance the dark mode persistence by modifying the theme's JavaScript. Here's a basic approach:

// Check for saved dark mode preference
const isDarkMode = localStorage.getItem('darkMode') === 'true';

// Apply dark mode if previously selected
if (isDarkMode) {
    document.body.classList.add('dark-mode');
}

// Update the toggle function to save preference across sessions
function toggleDarkMode() {
    const isDark = document.body.classList.toggle('dark-mode');
    localStorage.setItem('darkMode', isDark);
}

3. Consider a Dark Mode Plugin

If coding isn't your preference, several WordPress plugins offer comprehensive dark mode functionality that works across all pages:

  • WP Dark Mode
  • Darklup Lite
  • Dark Mode for WordPress

4. Clear Browser Cache

Sometimes, browser caching can interfere with theme functionality. Try clearing your browser cache and cookies, then test the dark mode toggle again.

When to Seek Further Help

If these solutions don't resolve the issue, consider checking the WordPress support forums for similar reports or reaching out to other Blogus users in community forums. Sometimes, theme updates address these types of functionality limitations.

Remember that theme demos often have limited functionality compared to the full installed version, so testing with an actual installation may yield different results.
