Common Errors of WordPress Theme with Solutions

Below is a wide selection of the most common WordPress theme issues and provides instructions on addressing each.

1. Customization and Updated Features Are Missing

You can personalize your theme in two ways. Utilizing either the Gutenberg editor or any builder or editing the main program file, you can alter the look of your theme. However, if you decide to edit the main program file, your modifications will be lost when you update your theme. On the other hand, customizing through an editor will keep the changes, so you don’t have to stress over updating. Therefore, if you have already changed your theme, wait to update it, as it will erase all the adjustments.

Solution: To ensure your customizations remain intact, create a child theme of the existing one and make the necessary changes there. Once you have done that, take the time to learn how to update WordPress properly without losing your customizations. This way, you can be sure that your work won’t be lost.

Suppose the functions.php file is the present theme. You must open the theme’s folder and right-click on functions.php to select View/Edit.
