A few PHP errors

[shyest]

I am trying to install a testsite to show my boss how we can sell items with Commerce however I am getting this error after I have uploaded all the IPS Commerce files.

 

Fatal error: Class 'IPS\Dispatcher\Front' not found in /data/13/1/56/80/1708569/user/1843703/htdocs/sos/joomla/store/index.php on line 13

 

 I also tried seeing if everything was ok with the system requirements with the ip4.php file and I get
 

MySQL Requirements

• You are not running a compatible version of MySQL. You need MySQL 5.0.3 or above. You should contact your hosting provider or system administrator to ask for an upgrade.
  
• Fatal error: Call to a member function fetch_assoc() on a non-object in /data/13/1/56/80/1708569/user/1843703/htdocs/sos/joomla/store/ips4.php on line 304

 

I will take care of the MySQL compatible version but not sure what the 2 fatal errors mean.

Thanks
