  4. Click Install on the Clean Grid theme, then click Activate.

Method 2: Upload via WordPress Dashboard

  3. Navigate to Appearance → Themes → Add New → Upload Theme.
  4. Click Choose File, select the clean-grid.zip file, and click Install Now.

  3. Upload the extracted clean-grid folder to /wp-content/themes/.
  4. Go to your WordPress Dashboard → Appearance → Themes and activate Clean Grid.

Troubleshooting Installation Issues

  • "The uploaded file exceeds the upload_max_filesize directive" – Your hosting limits file uploads. Increase the limit via php.ini, .htaccess, or contact your host. Alternatively, use FTP.
  • "The package could not be installed. The theme is missing the style.css stylesheet" – You may be uploading the wrong file. Make sure you upload only the clean-grid.zip file.

Import Demo Content

You can import the demo content, widgets, and Customizer settings shown in the Clean Grid theme demo.

Manual Demo Import

Step 1: Import Main Site Content

This includes: Posts, pages, menus, media, categories, tags, comments, and custom fields.

  1. Download: XML File
  2. Go to Tools → Import.
  3. Under "WordPress", click Install Now if not installed.

  3. Go to Appearance → Customize → Export/Import.

Regenerate Thumbnails

If your website already has existing posts with featured images, it's highly recommended to regenerate thumbnails after activating the Clean Grid theme. This ensures that all images match the new theme's layout and display sizes.

Regenerating thumbnails is optional if your site is completely new and doesn't have any uploaded images yet.

However, if you imported the demo content, regenerating thumbnails is essential to display images correctly across the site.

  1. Install and activate the Regenerate Thumbnails plugin.
  2. Go to Tools → Regenerate Thumbnails.
  3. Click the "Regenerate Thumbnails for All x Attachments" button to start the process.
  4. Wait until all images are regenerated. This may take a few minutes depending on your media library size.
  5. If you want, you can deactivate and delete the plugin once the process is complete.

This step ensures clean image alignment and sharp visuals throughout your website using the Clean Grid theme.

Header Image

Use the WordPress Customizer to add or manage the header image that appears at the top of your site.

How to add a header image

  1. Go to Appearance → Customize → Header Image.
  2. Click Add new image and choose/upload your image (suggested width: 1090px).
  3. Crop if prompted, then click Publish.

Header image behavior

  • The header image is displayed at the top of the site, above the header content area.
  • The header image automatically links to the homepage.
  • The image height is flexible, so you can use images of different heights.

For best results, use an image that is at least 1090px wide to match the theme's header width.

Translation & RTL

Clean Grid is translation-ready. It ships with a POT file for localization but does not include RTL-specific styles.

🌐 Translating the Theme

The theme includes a clean-grid.pot file located in the /languages folder inside the theme directory. You can use this file to create translations in your own language using any of the following tools:

After translating, save your files as:

  • clean-grid-[language_code].po
  • clean-grid-[language_code].mo

Place them inside the /languages folder in the theme.

↔️ RTL Language Support

RTL styles are not bundled with this theme. If you need RTL, add custom CSS or child-theme overrides after enabling an RTL site language.

Performance & SEO Tips

Here are some best practices to improve your site's performance and SEO when using Clean Grid:

  • Use a caching plugin — Install W3 Total Cache, WP Super Cache, or LiteSpeed Cache to improve page load times.
  • Optimize images — Use plugins like Imagify or EWWW Image Optimizer to compress images.
  • Use a CDN — A Content Delivery Network (e.g., Cloudflare) serves your content from servers closest to your visitors.
  • Install an SEO plugin — Use Yoast SEO or Rank Math to manage meta tags, sitemaps, and structured data.
  • Keep WordPress updated — Always use the latest versions of WordPress, themes, and plugins.
  • Minimize plugins — Only keep the plugins you actually use.
  • Use quality hosting — A good hosting provider makes a significant difference in performance.
  • Set featured images — Always set a featured image for posts to ensure proper display in the grid layout and when sharing on social media.
