Increasing image upload limit in Wordpress: No method is working

I don’t believe you can increase the limit from anywhere other than the main php.ini in use by the webserver (or the PHP process manager, FPM.)

The location of this varies from OS to OS so it’s difficult to know where to guide you.

Is this the one click Wordpress install (from the marketplace) running Debian 10?

Sorry I should have given more info.

I've got a Linode running a LAMP stack with Ubuntu 18.04 LTS.

I followed this tutorial which outlines how to change the main php.ini file. These changes are now live with a 16M limit, however all Wordpress sites on my server still show a 2mb limit in the Wordpress backend.

Thank you.

Edit: Some more info:

PHP version 7.2 is running and detected by Wordpress ("7.2.29-1+ubuntu18.04.1+deb.sury.org+1")

I've updated the php.ini file in /etc/php/7.2/apache2 with the following values:
memory_limit = 128M
upload_max_filesize = 16M
post_max_size = 8M

It looks like you're using the PHP module for apache(2)… Did you restart the web server after doing this?

After changing the php.ini file:

I ran sudo service php7.2-fpm restart

Then sudo systemctl reload apache2

Then rebooted my Linode through the dashboard

Still no luck.

OK, since you've definitively stated that you use php-fpm, /etc/php/7.2/apache2/php.ini was the wrong conf file to modify. You need to change the file /etc/php/7.2/fpm/php.ini.

/etc/php/7.2 is structured as follows:

cli <-- conf files for the the CLI: php(1)
fpm <-- conf files for the the FPM: php_fpm(8)
apache2 <-- conf files for the apache2(8) module
mods-available <-- conf files for the installed php modules

There may be some symlinks of files in mods-available in each of {cli, fpm, apache2}/conf.d/.

Also, in addition to php.ini, underneath /etc/php/7.2fpm are:

php-fpm.conf <-- the conf file for the FPM process
pool.d/ <-- the conf files for each of the FPM process thread pools

You restart php7.2-fpm with systemctl(1)…not service(8):

sudo systemctl restart php7.2-fpm

The command

sudo service php7.2-fpm restart

probably didn't do anything…

You should probably remove the package libapache2-mod-php if you don't use it:

sudo apt-get remove libapache2-mod-php

This will prevent you from modifying the wrong php.ini file in the future.

I can't speak to the "2mb limit in the Wordpress backend"…I don't know if that's a Wordpress limit or if WP is just parroting the PHP limit. If it's a WP limit, none of this is going to help you and you need to consult the WP docs.

Fantastic, thank you so much. Wordpress does indeed echo the PHP limit, and by following your advice I've managed to bump it up to 16mb.
