Ive inherited a silverstripe installation that is running for the most part but we have been unable to modify any content. When I logon to the admin pages I get the left side menu showing and the front page comes up ok, but when I click anywhere else I am generally getting a blank white box. I checked the php error logs and its showing
PHP Warning: Requirements_Backend::process_combined_files(): Couldn't create 'C:\inetpub\wwwroot/assets/_combinedfiles//lib.js' in C:\inetpub\wwwroot\framework\view\Requirements.php on line 1017
Im assuming the theme that is being used might have been designed for a system other than windows or was maybe customised incorrectly. Can anyone give me any pointers on how to fix the issue ?
