The uploaded file exceeds the upload_max_filesize directive in phpini

When I attempt to install the Universe theme because of the issues with using Middle Earth with bbPress, I get the following message: The uploaded file exceeds the upload_max_filesize directive in php.ini. Any suggestions in how to rectify either issue?

Hi!
By default, PHP permits a maximum file upload of 2MB. You can ask users to resize their images before uploading but let’s face it: they won’t. Fortunately, we can increase the limit when necessary. Two PHP configuration options control the maximum upload size: upload_max_filesize andpost_max_size. Both can be set to, say, “10M” for 10 megabyte file sizes. These options can be set in your server’s php.ini configuration file so that they apply to all your applications.
