Cause : Unknown


Solution
1. Delete "idx" directory from "apache-tomcat-7.0.59\resources\idx", it can contain stale index information, so let spagobi to rebuild the indexes.

2. I have fixed url as "ip:port/SpagoBI" in "server.xml" file
ex 192.168.1.1:8080/SpagoBI and i opened the SpagoBI on localhost instead of using IP.

So use correct URL you have defined in "server.xml" file.

3. I was having trouble with Chrome browser, so i switch to Firefox browser.
