Let’s make sure you use all helpful tools available to you in order to increase your WordPress upload limit size. Imagine we are grabbing coffee, I will make sure to explain each one to you:  

Editing php.ini File:  

This is a file that manages many PHP server settings. Open it up; you might need FTP or access through your hosting control panel. Look for the lines upload_max_filesize and post_max_size, and again change those values to something higher. After those changes, you’ll need to restart the server in order to let those settings take effect.

Modifying .htaccess File:
If you’re using an Apache server, you can adjust some settings directly in your .htaccess file. Just add a few lines like:
nginx
CopyEdit
php_value upload_max_filesize 64M

php_value post_max_size 64M

Save the file and check if the modifications are working. However, be careful about the changes made in htaccess as it can impact your entire site.

To make changes in wp-config.php:

Sometimes, including a line or two in your wp-config.php file might be beneficial. Try to add the following edit:

@[“upload_max_size”] php

Copy Edit

@ini_set( ‘upload_max_size’ , ‘64M’);

@ini_set( ‘post_max_size’, ’64M’);

This might help you set your limits at the specified time. Just open the file using a text editing program, and add the lines near the top after the opening tag of PHP and remember to save the file.

Altering Server Settings (through CPANEL or Hosting Server):

Most of the hosting providers will give you the option to modify the PHP settings directly through their control panels differing from other services. If you have CPanel, look for a ‘Select PHP Version’ or ‘MultiPHP INI Editor’ selection. From there, you can change the settings for upload_max_filesize and post_max_size without the need to modify any other files.

Using a Plugin for Increasing Upload Size:

If you’re not ready to make changes to the files or the server settings, there are certain plugins available that will help you achieve that. Plugins like ‘Increase Maximum Upload File Size’ allow you to set a new limit straight from the WordPress dashboard.

Getting in Touch With Your Hosting Provider: 

Sometimes it’s easier simply to reach out. If you are on a shared hosting account or if the other methods did not work, then try to contact your hosting provider. They will most likely lift the barriers for you.

Each of these methods has its advantages, and whatever approach you take depends on your level of experience and what sort of hosting package you’ve got. If one method isn’t successful, switch to a different one or ask for some help.
