In this guide, we’ll explain how to install a plugin in WordPress.
Plugins add extra features to WordPress, such as contact forms, security tools, backups, SEO features, image optimisation and e-commerce functionality.
Before installing a plugin, make sure it comes from a trusted source.
Where possible, use:
Avoid downloading modified or "nulled" plugins from unofficial websites, as these can contain malicious code.
The easiest way to install a plugin is through the WordPress Dashboard.
The plugin will now be active on your website.
Before installing a plugin, it is worth checking:
Plugins that have not been updated for a long time may no longer be compatible or secure.
Premium plugins and plugins downloaded directly from a developer are often supplied as a .zip file.
To install one:
.zip file from your computer.Do not extract the .zip file before uploading it unless the plugin developer specifically tells you to do so.
If WordPress displays an error because the plugin upload exceeds the maximum allowed file size, you may need to increase your PHP upload limits.
The relevant PHP settings are:
upload_max_filesize
and:
post_max_size
Cheap Host has a separate knowledgebase guide explaining how to increase the maximum PHP upload file size.
If you cannot upload the plugin through WordPress, you can also install it using your hosting File Manager.
First, extract the plugin files on your computer if necessary.
Then upload the plugin folder to:
wp-content/plugins
For example:
wp-content/plugins/example-plugin
Once the files have been uploaded:
If WordPress reports that the destination folder already exists, an older copy of the plugin may already be present.
Check:
wp-content/plugins
for a folder with the same plugin name.
Do not delete or replace plugin files unless you are sure you no longer need the existing version.
If the plugin is already installed, it may simply need updating or activating.
Many plugins require additional configuration after activation.
Depending on the plugin, its settings may appear under:
Check the plugin documentation if you are unsure where its settings are located.
Once installed, plugins should be kept up to date.
Go to:
Plugins > Installed Plugins
WordPress will display a notification when a new version is available.
Outdated plugins can cause compatibility problems and may contain known security vulnerabilities.
If you no longer need a plugin, it is usually better to remove it completely rather than leave it installed.
To remove a plugin:
A plugin normally needs to be deactivated before WordPress allows it to be deleted.
There is no fixed number of plugins that is automatically too many.
However, each plugin adds additional code to your website.
Poorly designed or unnecessary plugins can affect:
Only install plugins that provide a feature you actually need.
If your website stops working immediately after installing or activating a plugin, the plugin may be incompatible with your WordPress installation, theme or another plugin.
If you can still access WordPress:
If you cannot access the WordPress Dashboard, the plugin can normally be disabled using File Manager by renaming its folder inside:
wp-content/plugins
WordPress plugins are an easy way to add new features to your website.
For most plugins, simply search for the plugin from Plugins > Add New Plugin, install it and activate it.
Always use plugins from trusted sources, keep them updated and remove any that you no longer require.
