Does cs-cart3 work with php4? i.e. has this issue really been fixed:
Strict Standards: Declaration of SmartyEngine_Core::display() should be compatible
The dev was not able to reproduce the issue, likely because he was not using php5.4
CS-Cart 3 does not support PHP 4. It is stated in the official system requirements for CS-Cart that PHP 5.1 to 5.3 must be used.
PHP 5.4 is not yet supported, though we are working on it.
