Hire Kalium Developers

Kalium is a premium WordPress theme developed by Laborator and sold on ThemeForest with over 40,000 sales. It is designed for creative professionals and agencies – its portfolio display options, typography controls, and clean default design make it a popular choice for design studios, photographers, and creative consultancies.

Kalium bundles WPBakery Page Builder and Slider Revolution, and includes its own portfolio post type with multiple display styles (grid, masonry, justified, list). Its customiser covers header layout, typography, colours, and footer settings in detail. Laborator also maintains the Kalium Core plugin – a companion plugin that adds most of Kalium’s extended features, including the portfolio post type and demo import functionality.

Developer work on Kalium sites typically involves fixing issues that appeared after a Kalium, WPBakery, or Kalium Core update, customising the portfolio display beyond what the theme settings expose, setting up a child theme for ongoing maintenance, or optimising a Kalium site’s performance for better Core Web Vitals scores.

Kalium developer work typically involves:

• Bug fixing after Kalium or Kalium Core updates – identifying what changed and restoring the expected appearance or behaviour.
• Portfolio customisation – adjusting portfolio grid layout, hover effects, single portfolio page design, and category filtering beyond Kalium’s settings.
• Child theme setup and CSS customisation for brand-specific styling.
• Performance optimisation – reducing Kalium’s bundled plugin asset load and improving Core Web Vitals scores.
• WooCommerce setup within Kalium – configuring the shop to match Kalium’s design and adjusting product page layout.
• Demo import and brand adaptation – importing a Kalium demo and customising it for a specific client brand.

Kalium’s Kalium Core companion plugin adds most of the theme’s extended features. Look for developers who know both the theme and the Core plugin – the portfolio post type, demo import, and many customiser settings require Kalium Core to function.

For portfolio-focused projects, ask about their experience with Kalium’s portfolio post type and layout options. Kalium’s portfolio system is specific to the theme – knowing which portfolio layout settings produce which results, and where CSS overrides are needed for specific designs, requires Kalium-specific experience.

Common Kalium problems:

• Portfolio not displaying after Kalium update – Kalium Core is outdated or deactivated. Update Kalium Core alongside the theme and verify it is active.
• Kalium demo import failing – server memory or execution time limits are too low for the demo import process. Increase PHP memory_limit and max_execution_time before running the import.
• Custom CSS breaking after Kalium update – Kalium updated a CSS class that the custom CSS targeted. Move customisations to a child theme and review the Kalium changelog to update selectors.
• Kalium WooCommerce shop unstyled – Kalium’s WooCommerce integration is not enabled in the theme options. Enable it and check WooCommerce settings within the Kalium customiser.

Kalium, Kalium Core, and bundled WPBakery and Slider Revolution all need to be updated together. Laborator releases updates through ThemeForest. Always update Kalium Core alongside the theme – running a version mismatch between them is a common source of feature failures. Test updates on staging first.

Specify the Kalium version and Kalium Core version, describe what is broken or what needs to be customised, and include the page URL where the issue is visible. Note whether a child theme is already set up.
