WordPress is a very powerful application that allows us to configure out site many different ways. You may sometimes run into issues when trying to upload files (namely themes) through the WordPress administration page. Below we have outlined the steps needed to increase the upload limit.
Note: This article assumes that you are using at-least version 3.4.2. We cannot guarantee that this will work on version previous to 3.4.2. It is recommended that you upgrade to the most current version of WordPress for both compliance with this article, and security reasons.
If you are not using WordPress MultiSite, you can simply change your .user.ini file to allow for greater file-sizes to be uploaded.

If you are using Multisite, you will need to do two things.
1) Create a custom .user.ini file and increase the max upload limit set by php. For more information about this, please see the following link…
2) You will also need to edit the wp_sitemeta table inside the MySQL database. You are looking for the fileupload_maxk row. You will need to change this to something higher than it is. Normally 5000 will cover most uploads.
