First, you need to edit the wp-config.php file on your WordPress site. It is located in your WordPress site’s root folder. The wp-config.php fle is also known as WordPress configuration file which is used to set up the database connection.

As wp-config.php file is one of the most important files in your WordPress installation. wp-config.php file is found in your WordPress root directory and has a lot of information like database connection data, username, password, etc.

You will have to use an FTP client in your web hosting control panel. As FTP is known as File Transfer Protocol which is a fast and simple way to upload files from a computer to the website. As FTP allows to transfer files from one local computer to the remote website.

While using the FTP client where all  of your files are stored on your web host’s server, and by using FTP you can access these files from your computer. Any change that is made by you will be automatically applied on the server.

Next step, paste this code into a wp-config.php file just before the line that says ‘That’s all, stop editing! 

define( ‘WP_MEMORY_LIMIT’, ‘512M’ )

Once you are done with this step, save your changes and upload your wp-config.php file back to your server. This code tells WordPress to increase the PHP memory limit to 512MB.
