The functions.php file is one of the most sensitive parts of a WordPress website. It can be used to add useful functionality, but it can also quickly cause errors that block the frontend or the administration area.
For this reason, we do not recommend direct edits without a backup, a test environment and clear logic for the changes. For commercial projects, stability is more important than a quick workaround.
When it is worth editing
Editing it can be appropriate for theme-specific adjustments, hooks, filters or small features that do not justify a separate plugin. The code must nevertheless be documented and tested.
What to avoid
Avoid pasting code from untrusted sources, editing in production without verification and mixing functions together without organization. In many cases, a better approach is to use a child theme or a custom plugin.
Webhat can assess and implement changes of this type safely without compromising the website's operation.
