All the parameters in the link during installation are ok! But the problems appear after installation.
So we can sum some parameters we know:
+ PHP 5.3 or higher
+ Exec()function enable
+ System()function enable
+ MySQL
and what about other specific parameters?
- Zend Optimizer or Zend Guard and what version - ?
- Apache what version - ?
- and other...
Many people would like to install version 4.0 and will have problems with hosting, and when they have all specific parameters they can give them to their hosting provider to make server suitable for software.
