Increasing Maximum Upload File Size Limit on Wordpress and Raspberry Pi

so I'm hosting a Wordpress website on my Raspberry Pi 3B+ in my local area network LAN. The site is working OK.

The problem is, I can't seem to change the "Maximum Upload File Size" if I wanted to upload an image or even an already built WP site that is 180MB and migrate it to the Raspberry Pi. Default is 2MB.

This is the tutorial I followed: https://raspberrytips.com/wordpress-on-raspberry-pi/ I have researched online how to increase the maximum file size, and editing 4 files inside your WordPress project is what they recommend:

1. .htaccess (located in the root directory)
2. php.ini (located or create it in the root directory)
3. wp-config.php (located in the root directory)
4. functions.php (located wp-content/themes/astra)

THIS IS WHAT I HAVE ON EACH ONE OF THOSE FILES (I have tried with 256MB and 64MB):

.htaccess

php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value memory_limit 64M
php_value max_execution_time 300
php_value max_input_time 300

wp-config.php

@ini_set( 'upload_max_filesize', '64M' );
@ini_set( 'post_max_size', '64M' );
@ini_set( 'memory_limit', '64M' );
@ini_set( 'max_execution_time', '300' );
@ini_set( 'max_input_time', '300' );

php.ini

upload_max_filesize = 64M
post_max_size = 64M
memory_limit = 64M
max_execution_time = 300

functions.php

 @ini_set( 'upload_max_size', '64M' );
 @ini_set( 'post_max_size', '64M' );
 @ini_set( 'max_execution_time', '300' );

I ran the following commands after that:

sudo service apache2 restart
sudo service apache2 reload
sudo service mysql restart

Gave the server 5 minutes just in case since I've read it can take a while for changes...but the 2MB remained the same. I tried a plugin called:

I went to that plugin and set the maximum to 256MB and it changed the value....but when I tried uploading the 180MB already built site I want to migrate it gives me an error....but is accepts the upload and the progress bar reaches 100% but with an error.

This also happens with an image over 2MB even though the max upload file size was changed from 2MB to 256MB. Any help will do...thanks.
