What are Active and Installed plugins?

For WordPress, you can install a certain plugin and not use it if not needed. If you plan on using a plugin on your website, in that case, you need to activate it.

You can identify the active plugins by the blue highlighted background within the ‘Plugins’ page. Plugins that you see have a white background are not active.

Why can’t I install plugins on WordPress?

Reasons you cannot install plugins on WordPress are:

You are using the WordPress.com service – The most common scenario is, if you use a limited version of the renowned WordPress software. For you to install plugins, you need to upgrade to the business plan, requiring you to pay around $300/ year.

You have a memory limiting issue It means you can access and see plugins, but cannot install them. This failure is because of the PHP memory limit. When a certain process reaches its limit, you’ll either receive an error or the entire process ends.

Allowed memory size of 33554432 bytes exhausted (tried to allocate 43148176 bytes) in php

You can bring a quick fix to this issue by increasing the PHP memory limit. All you need to do is, add the following to your file named wp-config.php

define( 'WP_MEMORY_LIMIT', '96M' );

 

Restrictions for user roles WordPress has an integrated user role management system. You may not have administrator access, rather may have an editor account. If you do not have administrator access, then you can neither activate nor install a plugin within a WordPress site.

Collapse Menu in WordPress Dashboard

You are within a multi-site network – Your site may belong to a multi-site network. If the admin of this network disables the plugin menu, then you won’t be able to see it. The admin usually does this to maintain WordPress security and for load balancing.

Uploading wrong file format: For this, you’ll come across an installation error while manually uploading a plugin using the ‘Add New’ upload option within the WordPress site.

If you notice the “bad format” message, as shown below, then, this means, you did not upload the necessary native files that you got from the plugin developer.

The error message that you would get is supposed to be as follows:

Installing Plugin from uploaded file

Important Note:
“You should keep in mind that the only plugin which you should upload to your WordPress site is the zipped files. Make sure to cross check with the developer to know for sure if you’ve got the correct folder.”

There are missing files within the zipped file – Let’s consider that you’re trying to upload a zipped file on WordPress. However, you get the error message, shown below.

Therefore, the above message means, the files that exist within the given folder aren’t exactly what WordPress requires.

Therefore, what you need to do is, unzip the folder under question and proceed with reviewing its contents. Also, make sure that this is the correct zip folder.

In case of any missing files, we recommend you to contact your developers for help.

There are possibly syntax errors This is something that you shouldn’t be worried about if you buy a certain WordPress plugin from a reputed source.

— Although, you may come across either a “parse error” or “syntax error” message if you buy a plugin from an unreliable source with the hope of saving a few bucks. This error pops up while editing an already installed plugin.

On the other hand, if the error occurs during the installation process, in that case, this error lies within the developer.

File size exceeded You may also come to notice that the file size that is allowable has exceeded. When an error like this occurs, you will see a message as given below.

The uploaded file exceeds the upload_max_filesize directive in php.ini

Fixing maximum upload limit

  1. Go to the control panel
  2. Access your directory via file manager or FTP
  3. Search and locate the folder named wp-admin
  4. Now, if you do not see a file called php.ini, then you need to create one
  5. Next up, once you’ve opened the php.ini file, you need to lookup for the “filesize” section.
  6. You will be required to overwrite the file with the code, given below.

    upload_max_filesize = 1000M
    post_max_size = 2000M
    memory_limit = 3000M
    file_uploads = On
    max_execution_time = 180

  7. Making this change will provide you a leeway on the size of your WordPress plugin.

 

Word of caution
If you use any third party plugins, then, it is vital for you to check for its authenticity. You need to make sure that this does not put your site into any jeopardy.
**You need to proceed at your own risk, any other parties won’t be liable in case anything out of the ordinary happens.**

‘Add new’ button missing on WordPress plugin page. Why?

Some steps you can follow if the ‘add new’ button is missing are as given below:

Use another browser You need to ensure that this is not a browser related error. For this, open your website in another browser.

  1. If you see that upon opening your site the issue gets resolved, then you’ll know for sure that this was a browser specific error.
  2. However, if you still see the error, then the error wasn’t because of the browser you were using.

Manually updating it For this, you will need to download and unzip WordPress again. Then, you’ll need to proceed with accessing your server through the FTP or any other file manager from the control panel of your hosting account.

The next step will require you to delete and replace copies of all the documents within the server, except for the file wp-config.php as well as the /wp-content/ directory. This will replace all of your core files with no damage to either the settings or contents.

4. Can Inactive Plugins slow down my WordPress site?

WordPress plugins that are inactive are executable files. But, you should not worry because these files are harmless.

— Although, if anyone attempts to hack your site, these files may get infected. Hence, to ensure optimal protection for your website, delete any inactive plugins which aren’t used.

Ending Thoughts:

Plugins. If you do not use one on your WordPress website, it will look gloomy and out of sorts. This tool can pack some serious punch! We recommend you to do some research and get used to these small yet powerful packages to get the one that suits you best.

— Lastly, we recommend you to NOT overpopulate your WordPress website with too many plugins. Rather, be picky and use them wisely.
