PayPal fata error on Step 2 of funding page

Hi guys,
I’m getting the following error when trying to fund a project:

Fatal error: Cannot access protected property Error::$message in /home/funding4/public_html/wp-content/themes/funding_press/funding/lib/PayPal/Serializer/Unserializer.php on line 826

My PayPal app has been approved and i am using the live API details.
I have seen your sticky post and contacted hosting about Pear location.

They have replied with this:

found the path you need executing the following command:

Code:
php -c /usr/local/php53/lib/php.ini -r ‘echo get_include_path().”\n”;’

Here is the pear path you need to use on the case:

Code:
.:/usr/local/php53/pear

But i have no idea what i am supposed to do here. Please help
