Recently many php scripts are encrypted with ioncube loaders or zend encoder. Means they need special modules installed on your server to run properly.
Usually hosts install these modules on their servers along with php default installation. All you need to do is enable it at your web site level.
Bluehost and hostmonster web hosts made it very easy to install your php.ini file. This php.ini file contains paths to server ioncube installation. (Many other hosts are also having similar panel so try login into your cpanel and see if this works.)
STEPS TO INSTALL IONCUBE IN PHP.INI FILE:1. Login into your cpanel. Scroll down. You will see a link called ‘PHP Config’ under ‘Software/services’. Click on ‘PHP Config’ link.

2. After clicking on the ‘PHP Config’ link, look in the middle of the page. You will see a heading ‘Install Default php.ini’ file. Check the ‘Ioncube’ check box and click on ‘Install php.ini master file’. You will see a message php.ini.default file is created in your ‘public_html’.
Now ftp into your web site and go to ‘public_html’ directory. You will see ‘php.ini.default’ file there. Rename it to php.ini. (Remove ‘.default’ part)

3. Now open a browser and access the script in a way that your script author says in the installation guide.
You should access it correctly without any ioncube loader error.
IF STILL YOU ARE NOT ABLE TO ACCESS THE SCRIPT AND GETTING IONCUBE ERROR TRY THIS:1. Follow the step 1 as above.
2. You will see three radiobutton options. (See the image below)
3. Select the option ‘PHP5 (Single php.ini)’ and save.
4. Now access your script through the browser. You should be able to access it now.
