Code:
Warning: require_once(include/xbtit_version.php) [function.require-once]: failed to open stream: Permission denied in /opt/lampp/htdocs/install.php on line 42
Fatal error: require_once() [function.require]: Failed opening required 'include/xbtit_version.php' (include_path='.:/opt/lampp/lib/php') in /opt/lampp/htdocs/install.php on line 42
How can I solve this?
