The Author hReview plugin requires the ionCube PHP Loader to be installed on your web hosting, in most cases you will have it already installed but (not activated), just follow these steps:
1- Login to your cPanel.
2- Under the Software/Services category, click on the PHP Config icon.
3- Inside of this, you will find the option to select Ion Cube
4- Select this and hit Save Changes
The other way to go is to contact your web hosting and ask for their assistance, or if you are the website operator please use the ionCube Loader Wizard to assist with installation.
I am contacting Godaddy with this issues And following is the reply I Got
Thank you for contacting Online Support.
I understand you are asking about your ioncube.
By default, ionCube support is not enabled on our Linux hosting accounts, but you can enable it. Windows hosting
accounts do not support ionCube.
NOTE: Before enabling ionCube support, you must enable Zend Optimizer. The ion cube lines of script must be above the Zend Optimizer script in the php.ini or php5.ini file. For more information, see Using Zend Optimizer.
To Install ionCube
Download the compressed Linux x86 binary file from ionCube's site. We recommend using the ZIP file.
Upload the compressed file to your hosting account. For more information, see Uploading Files Using the FTP File Manager.
Unarchive the compressed file in your hosting account. For more information, see Unarchiving Files and Directories with Your Hosting Account.
NOTE: Unarchiving the compressed file creates the necessary /ioncube directory.
Add the following lines of script to your php.ini file using PHP4 or php5.ini file using PHP5 to reference the absolute path to the binary:
NOTE:: If your account does not have a php.ini or php5.ini file, you must create one.
To find your absolute path, see Finding Your Hosting Account's Absolute Path.
Replace "X.X" with "5.2" using PHP5.2 or “5.3” if using PHP5.3. See Programming Languages in your Hosting Control Center to see which version you have.
NOTE: The zend_extension script must appear as the first line after [Zend].</font>
