   This is a great guide for beginners. I especially liked the step-by-step screenshots. However, I should add that before installing any plugin, it’s always a good idea to back up the WordPress site… just in case something goes wrong.

     That is a good safety suggestion especially when installing larger plugins.

   Wordpress plugins are a great thing, but I would totally disagree with the statement in the FAQ article that you can install as many plugins as you need. You are minimally limited by the memory limit, which is set on the hosting and which will eventually run out. I think that a reasonable solution is up to 20 plugins. Then the amount will start to show on the speed of the website. A combination of plugin and snippet is good. If not everything can be solved immediately with a plugin, and there is a snippet for many problems.

     It heavily depends on the plugin for how much they would affect a site, we would recommend taking a look at our article below:

   Most often I use the first method by going through the plugin options and searching in the WordPress repository.
   it does make a lot of sense in terms of knowing that the repository is always safe to use.
   I have used upload methods as well mostly for premium plugins as they come directly from plugins own websites.
   Much appreciated the efforts of wpbeginner to make even the simple things more simple.

     It sounds like you are either installing a massive plugin or there may be an issue with your hosting, we would recommend reaching out to your hosting provider to ensure there is no error from their end.

    Hi. I’m uploading a plugin like in the second example…. but which file do I upload? The maps one I have purchased is a folder with all the files inside i.e. documentation – I don’t know which bit to upload! Please help

    返信

    • WPBeginner Support

      Hi Rose,

      When you purchase a WordPress theme you get it in a zip file. You don’t need to unzip that file and upload it.

      You try again by downloading the plugin again.

      Alternately, you can upload the plugin folder to your WordPress website manually using FTP. You will need to upload the folder to /wp-content/plugins/ folder.

    BUT: When I have installed and activated, what do I do then to use the plugin??

    返信

    • WPBeginner Support

      Hi Niels,

      It actually depends on the plugin you are using. Some plugins add a new page where you can configure plugin settings. This page is typically located under Settings menu in your WordPress admin bar. Other plugins may place it under other menu items in admin area. Check the plugin’s details page for instructions.

    Hello,

    I would love some assistance with a plugin please. I have uploadd a new theme to my site with all of the required plugins, all of which have successfuly installed, but one (Revolution Slider).
    I am getting the following message:

    Unpacking the package…
    Installing the plugin…
    Destination folder already exists…./public_html/wp-content/plugins/revslider/
    Plugin install failed.

    I have gone into my file manager and can see that there is already a folder with the required plugin installed, however when I try to access the plugin from the WP dashboard, it still says it’s not been installed (and I can’t find it in inactive either).

    If anyone has any advice, I’d be super grateful! Thanks!

    返信

    • WPBeginner Support

      Hi Martyna,

      You’ll need to delete the plugin folder from your website using the File Manager. After that you’ll be able to upload and install the plugin again.

    Hi

    How do I install a plugin in localhost?

    I’ve tried adding it manually in : xampp/htdocs/mywebsite/wp-content/plugins

    but when I got back to the site plugins area its still not there. I’ve cleared cache just in case there was a bit of a lag but still nothing.

    I used this process to add a new theme and it worked fine.

    Is there something else I should be doing?

    Thanks

    返信

    • WPBeginner Support

      Hey Deborah,

      May be the plugin you are trying to add has incorrect plugin header which could stop WordPress from showing it as a plugin. Try adding some other plugin, to make sure this isn’t the case.

    Hello, thanks for the great info. I’ve purchased Yoast premium, downloaded it, but then when i try to upload to my site, its has broken the download into a bunch of individual folders. I’m certain i probably need all of them, but it will only let me choose one?
    So how should i proceed?

    返信

    • WPBeginner Support

      Hi Brock,

      Premium plugins come as a zip file. After downloading it to your computer, you don’t need to unzip or open that file. If you do that, then you will see individual folders packed inside the plugin.

      If for some reason you cannot locate the plugin’s zip file, then you can try uploading it using FTP.

      Hi Gelu Nastac,

      First you will need to deactivate the plugin. If you are unable to access the WordPress admin area, then see our guide on how to deactivate plugins when not able to access admin area.

      After that you will need to install the updated version of the plugin. Let us know if this worked.

    I would like to ask for help on plugins. I’m new to this area and I’m currently taking an online course. However, I haven’t gotten an answer from them yet.

    I’m trying to activate/add my first plugin. I understand a plugin can be 1 file. In my case it’s a php file and its contents is just comments at this point.

    When I go to plugins in my admin site I dont see the file. so I’ve tried using the ‘add new’ link and I proceed to upload the file both as a singe file and as a zip file and here are the errors I get:

    Unpacking the package…

    Installing the plugin…

    The package could not be installed. No valid plugins were found.

    Plugin install failed.

    OR i get this error:

    Unpacking the package…

    The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature

    I’ve installed XAMPP and Wordpress on my local host

    Why am i getting these errors and how do I correct it?

    How do I add my plugins that I develop myself to my site? I’m using my localhost with XAMPP to do testing

    Thank you.

    返信

    • WPBeginner Support

      If you cannot see the plugins menu, then most probably your site is still redirecting you to the WordPress.com dashboard. It is also possible that your site is still hosted with WordPress.com and you just added a domain name to your existing WordPress.com blog.
