Hi @Altaf_Bankotkar,
That’s an issue with your web server configuration, rather than OJS; here’s a thread with some suggestions on how to set up your web server so that the PATH_INFO variable works as it should: About Restful Url with PHP CGI/FCGI - #2 by asmecher
I’d suggest spending some time getting it working with a test script, then come back to OJS and see if that fixes things.
