Installation

Good afetrnoon,

I’ve just bought Splah and when I try to install the demo version, I get this message, do you have an idea how I can resolve these issues ? 

Fatal error: Uncaught Error: Call to undefined function cache_get() in /homepages/35/d648484838/htdocs/includes/module.inc:754 Stack trace: #0 /homepages/35/d648484838/htdocs/includes/module.inc(954): module_implements('system_theme_in...') #1 /homepages/35/d648484838/htdocs/modules/system/system.module(2511): module_invoke_all('system_theme_in...') #2 /homepages/35/d648484838/htdocs/includes/theme.inc(798): _system_rebuild_theme_data() #3 /homepages/35/d648484838/htdocs/includes/theme.maintenance.inc(57): list_themes() #4 /homepages/35/d648484838/htdocs/includes/bootstrap.inc(2857): _drupal_maintenance_theme() #5 /homepages/35/d648484838/htdocs/includes/errors.inc(179): drupal_maintenance_theme() #6 /homepages/35/d648484838/htdocs/includes/bootstrap.inc(2594): _drupal_log_error(Array, true) #7 [internal function]: _drupal_exception_handler(Object(ParseError)) #8 {main} thrown in /homepages/35/d648484838/htdocs/includes/module.inc on line 754
