 internal error or misconfiguration in codeigniter or php Internal Server Error  The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator , admin@localhost and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log. so please Make sure your apache has mod_rewrite activated LoadModule rewrite_module modules/mod_rewrite.so If it is commented out (# in front), make sure to uncomment it and save the file. Checking if the corresponding module exists may be a good idea as well (but it usually does). IN simple language go on your running wamp or xampp click on that  and go on apche section and click on httpd.conf file and search mod_rewrite.so and remove the # in the front of line (# is use for comment)

To configure url redirection in apache in xampp Or enabling mod rewrite in xampp You should follow these steps for enabling mod rewrite in xampp To enable mod_rewrite in xampp first go to the directory of installation <xampp-directory>\apache\conf   and edit httpd.conf . Find the line which contains #LoadModule rewrite_module modules/mod_rewrite.so uncomment this line means remove hash(#) front of this line (should be): LoadModule rewrite_module modules/mod_rewrite.so Also find AllowOverride None  Should be: AllowOverride All I really think it appears 2 or 3 times on the configuration file. Happy xampping!
