Why is my viewing function in WERA cannot function?
1. I cant show the viewing link in WERA.
2. It shows something like these on next page
Warning: Invalid argument supplied for foreach() in /opt/lampp/htdocs/wera/lib/seal/nutch.inc on line 196
Warning: Invalid argument supplied for foreach() in /opt/lampp/htdocs/wera/overview.php on line 132
3. I have installed all the prerequisite software such as hadoop, nutchwax, apache-tomcat, lampp.
