How to Change WordPress Memory Limit Step-by-Step?

If you’re running a WordPress site, you might have encountered issues related to insufficient memory.

These issues can cause your website to slow down or even crash, impacting both user experience and your site’s performance.

Fortunately, increasing the memory limit for your WordPress site can often resolve these problems.

In this post, I’ll guide you through four methods to change your WordPress memory limit, helping you keep your site running smoothly.

Editing wp-config.php

One of the most effective ways to increase your WordPress memory limit is by editing the wp-config.php file.

This method is preferred because it directly targets WordPress’s memory allocation without affecting other applications on your server.

Here’s a step-by-step guide:

1. Access Your WordPress Files
   Use an FTP client or your hosting provider’s file manager to access your WordPress files.
2. Locate the wp-config.php File
   Find the wp-config.php file in the root directory of your WordPress installation.
3. Edit the wp-config.php File
   Open the file for editing. Look for the line that says /* That's all, stop editing! Happy blogging. */.
4. Add the Memory Limit Code
   Above that line, add the following code to increase the memory limit:

   define( 'WP_MEMORY_LIMIT', '256M' );

Replace 256M with the amount of memory you wish to allocate (e.g., 128M or 512M).

5. Save Your Changes
   Save the wp-config.php file and upload it back to your server.

Editing .htaccess File

If you can’t access or edit the wp-config.php file, you might use the .htaccess file instead.

This file controls server configurations, so be cautious as changes can affect other applications on your server.

1. Access the .htaccess File
   Use your FTP client or file manager to locate the .htaccess file. If it’s hidden, enable the “show hidden files” option.
2. Edit the .htaccess File
   Open the file for editing. Add the following line at the beginning of the file:

   php_value memory_limit 256M

Replace 256M with your desired memory limit.

3. Save Your Changes
   Save and upload the .htaccess file back to your server.

Editing PHP.ini File

Another method to increase your memory limit is by editing the PHP.ini file. This approach affects the PHP configuration for your entire server, not just WordPress.

It’s a good option if you manage multiple PHP applications.

1. Access the PHP.ini File
   Depending on your hosting provider, you might be able to access and edit the PHP.ini file directly through their control panel or via FTP.
2. Locate the memory_limit Line
   Find the line in the PHP.ini file that reads memory_limit = 32M (or a similar value).
3. Change the Memory Limit
   Modify the value after the = sign to your desired memory limit:

   memory_limit = 256M

4. Save the File
   Save your changes. Be aware that some servers may require a restart for the changes to take effect.

Contacting Your Hosting Provider

If you find that none of the above methods work or if you’re unsure about making these changes yourself, contacting your hosting provider is a wise choice.

They can advise you on server limitations and may be able to increase the memory limit for you.

Important Considerations

Before increasing your memory limit, it’s essential to understand why you’re encountering memory issues.

Sometimes, optimizing plugins and themes can resolve memory problems without needing to increase the limit.

Also, keep in mind that server limitations might restrict the effectiveness of your changes.

Be cautious when setting a very high memory limit, as it can impact server performance.

Conclusion

In conclusion, adjusting the WordPress memory limit can help resolve performance issues and improve your site’s speed.

Whether you choose to edit the wp-config.php, .htaccess, or PHP.ini files, or reach out to your hosting provider, each method has its own set of considerations.
