Check whether MySQL server is running at all  If you not run apache server or any server you use  this could happen  After run your local server and refresh the page

I had the same problem and I searched a lot in web but no solution worked for me  finally I noticed by chance that mysql is using port 3308 instead of port 3306 which seems to be default     I changed the port to 3306 and surprisingly it worked          my problem was in connecting php to mysql database  php my admin page was shown perfectly

If the WAMP icon is Orange then one of the services has not started    In your case it looks like MySQL has not started as you are getting the message that indicates there is no server running and therefore listening for requests    Look at the mysql log and if that tells you nothing look at the Windows event log  in the Windows - gt  Applications section  Error messages in there are pretty good at identifying the cause of MySQL failing to start   Sometimes this is caused by a my ini file from another install being picked up by WAMPServers MySQL  normally in the  windows or  windows system32 folders  Do a search for  my ini  and  my cnf  and if you find one of these anywhere outside of the  wamp     folder structure then delete it  or at least rename it so it wont be found  Then restart the MySQL service
