Fatal error: Class 'shopFunctionsF' not found in /.../mod_virtuemart_product.php

[BaidareW]

With Opera browser everything works OK, but with all other browsers I get "Fatal error: Class 'shopFunctionsF' not found in /domain/public_html/modules/mod_virtuemart_product/mod_virtuemart_product.php on line 75 "

This happens when I enable product module with recently viewed products.

VM 3.0.6.4 and joomla 3.4.1

Any thoughts about it ?

Updated to latest VM 3.0.8 and problem gone.
