Increasing the Server Max Upload Size

All SpinupWP servers are configured with a default maximum upload size of 64MB. However, you may increase this limit if you need to allow larger files to be uploaded via the Media Library.

Each site is also deployed with a PHP-FPM resource pool, which is owned by the site user. This prevents…
