Self-hosted Wordpress and unable to successfully adjust the upload_max_filesize

I copied the latest wordpress onto a Linode ubuntu 20.04 server using cURL and was able to deploy it live with apache2 and custom DNS, but have been unable to upload a PRO plugin due to PHP upload_max_filesize issue:

I ran php --ini on the server and here is the output:

In /etc/php/7.4/cli/php.ini, I updated upload_max_filesize (higher and higher all the way up to 512M) and post_max_size and restarted apache, but still hitting the same error. Also added the Upload filesize plugin and set that pretty high as well: enter image description here

At this point I'm wide open to ideas on how this can be resolved. The error message seems pretty cut and dry.

I also attempted to add @ini_set('upload_max_size' , '256M' ); to the wp-config.php to no avail and created a test.php file that echoes the value of upload_max_filesize, which does echo as expected.

Solution

  • Which ini file will be used that depends on the module. You need to edit these configuration files for a wider compatibility:

    /etc/php/7.4/apache2/php.ini
/etc/php/7.4/cgi/php.ini
/etc/php/7.4/cli/php.ini

    Alternatively, you can create an user.ini file.

    Also, you have to edit at least:

    memory_limit
max_post_size
upload_max_filesize

    Where value of memory_limit > max_post_size >= upload_max_filesize. For example, you can set the values 10MB, 8MB, 6MB or 8MB.
