Multisite stuck at 1MB for max file size

The question:

I have a WordPress Multisite install on our FreeBSD development server. It seems to be stuck at 1MB.

I have the following settings in php.ini

upload_max_filesize = 100M  
post_max_size = 100M  
max_execution_time = 300  

All the regular WordPress installs on the site have a max upload size of 100MB, as expected. Regardless of the values I put the multisite install is stuck at 1MB.

The setup:

  • FreeBSD 8.1
  • PHP 5.3.3
  • WordPress Multisite 3.2.1

After moving the site to another server on Rackspace, it has the same issues.

Any help on getting this limit raised would be appreciated. If I left any pertinent information out let me know and I’ll provide what I can.

The Solutions:

Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.

Method 1

There is a network admin settings page with a Max upload file size field, make sure this is also set correctly.
