FAQ Frequently Asked Questions

Which is better, free themes or paid themes?

It depends on your specific needs. Free themes are suitable for blogs or small websites with limited budgets and simple requirements, but they may have limitations in terms of functionality, support (usually only available through community forums), and frequency of updates. Paid (premium) themes typically offer more advanced features, a wider range of design options, more reliable customer support, regular updates, and security patches, making them ideal for businesses, e-commerce sites, or websites that require unique functionalities.

How to determine whether a theme is fast enough in terms of performance?

You can use online speed testing tools on the demonstration website for the topic (for example,...).GTmetrix、PageSpeed InsightsEvaluate the website by checking its loading time, page size, and performance scores. Also, verify whether the theme follows best coding practices. For example, check if there is excessive use of inline styles and scripts, as well as whether a large number of dynamic animations or sliders are implemented, as these can potentially slow down the website’s performance.

Is it safe to change the theme of a website that is already live?

Changing the theme carries certain risks, as it may affect the appearance of the website and some of its functions. Before making the change, be sure to conduct a thorough test in a local environment or on a temporary site using the “Maintenance Mode” plugin. Verify that all page layouts, custom features (especially those set through shortcodes or theme options), menus, and widgets are working correctly. It is essential to back up the entire website and its database first.

Are subtopics mandatory to create?

If you plan to make any code-level modifications to the theme (including CSS styles, PHP functions, or template files), it is highly recommended to create a sub-theme; this is considered the best practice. If you only use the theme’s built-in option panel and page builder for customization without altering any code files, then you may not need a sub-theme. However, for the sake of long-term maintenance, it’s a good habit to start using sub-themes from the beginning.
