Downloading The Plugin
Go to your CodeCanyon Downloads page, locate the plugin, click the green Download button and select the All files & documentation option.
There are two ways to install the plugin, through the WordPress dashboard or through FTP.
Installing Through WordPress Dashboard
Step 1: Unzip the zip file you downloaded and you should see a folder called “ultimate-reviewer-plugin”.
Step 2: Log in to the WordPress Admin Panel.
Step 3: Go to Plugins > Add New.
Step 4: Click the Upload Plugin button and upload the ultimate-reviewer.zip file inside the”ultimate-reviewer-plugin” folder.
This error is most likely occurring because your server’s upload limit is too low. Currently the plugin is around 13MB.
Increase the PHP Memory Limit, Post Maximum Size and WordPress Upload Limit values as explained in the Theme Requirements table below.
Installing Through FTP
If the plugin is too large to be uploaded through the WordPress admin panel you should upload the plugin through an FTP client instead. To set up an FTP client refer to the WordPress documentation on this http://codex.wordpress.org/FTP_Clients.
Once you have set up your FTP client upload the ultimate-reviewer plugin folder to /wp-content/plugins/ directory on your server.
Activating The Plugin
Once you have installed the plugin, you can activate it by going to Plugins > Installed Plugins and clicking the Activate link below the plugin name.
