Class Customization not found (error)

[GDPT]

Hello

My web works perfectly on localhost (my laptop), But It has been getting some errors since I published it to a free hosting.

My web is based on prestashop 1.6.0.5 : http://pt.onlinewebshop.net

I always get an error whenever I view order detail like this: "Fatal error: Class 'Customization' not found in /..../www/pt.onlinewebshop.net/classes/Product.php on line 4063".  The file Customization.php has been already exist in "/pt.onlinewebshop.net/classes".

Please help me to solve the above error, thank you for reading.
