How to install a WordPress Plugin

What is a WordPress plugin? A comprehensive guide.

A WordPress plugin is a piece of software that once installed onto a WordPress website will extend its functionality or add new features.

The scale of a WordPress plugin can be from small, tweaks and enhancements like adding a contact form; up to hudge features such as transforming a website into a fully-featured eCommerce store.

On the techie side of things, a WordPress plugin is a group of functions often written in PHP and JavaScript. The plugin will generally make use of WordPress action hooks, filters and functions to build upon the existing framework.

What does a WordPress plugin do?

WordPress plugins extend the way WordPress functions adding unique features to a website; without having to modify WordPress at its core level.

There’s no set task that WordPress plugins will do; rather, it depends on the developers’ requirements and desired outcome.

Here’s a shortlist of some of the more advanced things a WordPress plugin can add to a website:

  1. eCommerce functionality.
  2. Contact/newsletter forms.
  3. Forum functionality.
  4. Images/Video galleries.
  5. Quizzes, Popups and Surveys.

What should I know before using a WordPress plugin?

Before installing a new plugin to your site, you should take note of what version of WordPress you’re using, as well as what you’re aiming to achieve.

There are a few questions that you should try and answer before jumping into a new plugin install.

Should I use a free, premium or bespoke plugin?

Not all plugins get coded equally. There are three tiers to WordPress plugins to take note of, free, premium and bespoke.

Free plugins cost no money and are often suited for the needs of most people. They are a great way to add smaller features to your website but, tend to have limited functionality with a call to action to purchase a premium version.

Premium plugins can cost between £10-1,000s, depending on your requirements. They will generally offer more features than their free counterparts, as well as come with support and regular updates.

Bespoke plugins are custom made specifically for you. They can cost considerably more than the other options but have the benefit of working exactly how you need them to.

Is a plugin safe to use?

Like anything, downloading a plugin can come with risks. But, if you’re careful and do your research, you can stay safe. Just be sure to:

  1. Use plugins from reputable developers and directories.
  2. Look at the reviews of the plugins
  3. Take note of the last time a plugin was updated.

If you’re looking for free plugins then you’re the best choice is browsing the WordPress repository.

Is the plugin compatible with my website?

A reputable plugin developer will say which version of WordPress their plugins work on. Be sure to take note of your WordPress version and install only the one that works on your WordPress version.

Installing plugins for an older or newer version of WordPress can cause some huge problems.

Why can’t I install a WordPress plugin?

There are a few reasons why you might not be able to install a WordPress plugin. Here are a few common issues.

I can’t see a Plugin item in my WordPress menu.

If the plugin menu item isn’t visible, there are two possible reasons.

The first is that you don’t have permission to manage plugins on your website. You can verify if this is the cause by navigating to yourdomain.co.uk/wp-admin/plugin-install.php while logged in. If you don’t have permission, you’ll see a message saying so.

To fix the issue, contact your websites admin, or developer and ask them to give you permissions to install plugins.

The second reason could be that you’re website is using WordPress.com instead of WordPress.org. WordPress.com is a hosted solution that doesn’t allow you to install plugins.

To solve the issue, you’ll need to look at migrating your website to another hosting provider. We recommend Krystal.

While installing a plugin, I get an error message.

If you’re installing a plugin through the WordPress admin dashboard; you may occasionally get an error message along the lines of “Could not create directory.” 

If that’s the case, there are three potential reasons:

  1. Your web server is out of disk space.
  2. Your web server has strict permissions on the plugin folder.
  3. Your web server has an upload file size limit.

In all three instances contacting your hosting provider should result in a timely fix.

I installed a plugin; now, my website won’t load.

Contact your hosting provider and ask them to rename the folder of the plugin you just installed. If you have FTP know-how, then you can rename it yourself for a faster fix.

Basically, by renaming the plugins folder, it will deactivate the plugin and won’t run the problem code anymore. You can then login to the WordPress dashboard and either find a fix or delete the plugin.

Generally, this issue is due to incompatibilities with the plugin and your web server, or WordPress version.
