WordPress Overview and Structure
WordPress is a content management system used to create and manage a website through a browser-based dashboard. The core software provides publishing, users, media and settings. Themes control presentation, while plugins add or change features.
The main parts of WordPress
- WordPress admin: the private management area, usually reached at
/wp-admin/. - Core: the WordPress application and its built-in features.
- Theme: controls templates, layout and visual styles.
- Plugins: extend WordPress with features such as forms, ecommerce or caching.
- Media Library: manages images, documents and other uploaded files.
Files and database
WordPress code, themes, plugins and uploads are stored as website files. Pages, posts, users, settings and plugin data are stored in the database. The wp-config.php file connects the installation to its database and holds important configuration.
Keep the parts working together
WordPress core, the active theme, plugins, PHP and hosting all need to be compatible. Create a backup before significant changes, apply updates from trusted sources and test the public site after updating. BugShield maintenance plans include monitoring and developer-managed maintenance for the covered site. See Understanding Maintenance Plans for details.
Common questions
Frequently Asked Questions
What is the difference between a theme and a plugin?
A theme primarily controls how the site is presented. A plugin adds or changes functionality, although some themes also include their own features.
Where is WordPress content stored?
Written content and settings are stored in the database. Images and other uploads are normally stored as files under wp-content/uploads.
Can I manage WordPress without accessing the hosting account?
Many everyday tasks can be completed in WordPress admin. Hosting access is still needed for server settings, files, databases, DNS and some troubleshooting.
Does updating WordPress also update every plugin and theme?
No. WordPress core, themes and plugins have separate updates. Review each one and keep a current backup before making significant changes.
