The language is quite dynamic with various functional sides. Some of its works include performing calculations, processing queries related to WordPress, and many other functions. The memory space is the most important aspect of a fully functional PHP WordPress.

Every WordPress has a memory limit. The PHP memory limit of WordPress is from 32MB to 64MB.

If you have a single site running, the WordPress limit will be somewhere around 40MB. After crossing the limit, the fatal error message will be seen on the site.

On the other hand, having multisite working together will increase the wp memory limit to a maximum of 64MB. As a result, the optimum required memory is often said to be 128MB.

However, you may end up needing more space if the plugin requires it. So that you can easily check the memory usage after activating the server IP and the display plugin of the memory usage.

Why You May Need More Space on WordPress

Increasing the limit on WordPress can be a quick adjustment to any sort of error you may face. However, you must be careful not to get too much space as it can make your site inefficient.

One major reason why you would need more space on WordPress is that you require more space to upload the contents of your site.

Sometimes, running the plugin with an old version can make the site inefficient and slow. As a result, you may need to increase the space to upgrade the version to enhance the performance.

Different Types of Memory Limit in WordPress

You can find two types of memory limits in WordPress. These are the administrative and the public memory limit.

Administrative Memory Limit

The administrative memory limit is the limit for admin pages. Similarly, this is generally the owner’s page of the website.

As admins or owners of a webpage, you are entitled to a limited amount of space to code the contents of the page. This space limitation is called the administrative memory limit.

Public Memory Limit

The public page of the website is simply the landing and other pages available for public users. The hosting server again allows limited space for public pages. The limited space is called the “public memory limit.”

How to Increase WordPress Memory Limit: 3 Effective Methods

At any point during your function, you will definitely need to increase the WordPress memory limit.

This is true to increase the Administrative Memory Limit as well as to increase Public Memory Limit. There are 3 different ways in which you can do this.

Editing the wp-config.PHP file

The wp-config.PHP file contains the details of the base configurations of your site. This is the root of the file directory of your WordPress.

First, you will need to search for this line: define (‘WP_MEMORY_LIMIT’, ’32M’);. After finding this line, you will need to modify the last number and increase it.

Now, that last number is basically the space limit. Therefore, you should increase it to 128M at least. In the end, the line should look like this: define(‘WP_MEMORY_LIMIT’, ‘128M’);.

When you are done increasing the memory limit, you should remember to save it. You can still increase the memory if you need to in the future. However, you should not overdo anything as that can crash the server.

Editing the PHP.ini file

This is the method used when the first method does not work. Sometimes, you may not be able to fix the PHP increase memory limit problem just by increasing the WordPress memory.

In such circumstances, you will have to go to the server settings. However, you must not be using a shared server for this process to work.

If the server you are using is private, you can find the PHP.ini file in the root folder. Once you find it, you should make the following changes:

  • memory_limit = 256M
  • upload_max_filesize = 12M
  • post_max_size = 13M
  • file_uploads = On
  • max_execution_time = 180

You should input the value that suits your interest as well as solves the memory limit error. Moreover, you must clear the cache to check whether the changes solved the issue or not.

Editing the  .htaccess file

This is the last option you can use. This is your last resort when the previous method does not work.

The dot in front of the file name suggests that it is hidden. As a result, you will find it in the SFTP manager if you do not find it in the root folder.

However, increasing the memory limit with this process is much easier. All you have to do is add a few commands in the .htaccess file. These commands are as follows:

  1. First Command: php_value memory_limit 256M
  2. Second Command: php_value upload_max_filesize 12M
  3. Third Command: php_value post_max_size 13M

Why WordPress Memory Limit Error Shows Up?

Your website will require enough data to store all the contents. Whenever there is a shortage of available space, the memory limit error will show up. It is just as simple as that.

However, the question is why the memory would run out if it is finishing up unexpectedly. Just like any other website, your website should go through updates and upgrades with time.

Similarly, this will cause newer plugins and scripts to be stored on the server. With all the new contents, the available space will keep on clustering every day.

Eventually, you will see the WordPress memory limit to be filled up and show an error message.

How to Check Current Space in WordPress

You can easily check the current memory space of your WordPress. This can be checked in the Site Health Tool.

At first, go to the WordPress dashboard. Then, there you will see “Tools”. Click on it, and you will find the “Site Health” option. Inside this option, you will see “Info”.

Click on it and check the server section. There you can see the PHP Memory Limit.
