I am trying to install **Fris Social share** in my `Magento 1.9.3` store.

I am getting the following error after installation:

> 
> Fatal error: Class 'Fris\_Socialbuttons\_Helper\_Data' not found in D:\xampp\htdocs\magento\app\Mage.php on line 547
> 
> 
> 

I have `disabled` Compilation in **admin>system>tool>compilation** its working fine, but when I `enable` Compilation, it shows above error.

Following code in `app\code\local\Fris\Socialbuttons\etc\config.xml`

```
