problem after server change to vps

Hey This is clearly the issue of your Database connection. 

Please make sure these things. 

1. Your Database Host is correct in lib >> db_connect.php ? is it localhost if yes then confirm with your web hosting your correct DB host

2. Please make sure your Database name is correct. 

3. Your Database User name and password is correct. 

4. Your Database is linked with your user. 

Please confirm these things and your issue is core related to your DB connection. thanks

Where you created DB that information also. So i can check what's problem with your DB settings. 

Please check your application 

in common folder, try to check your db logins. This is not related to my script its either related to your customizations or your hosting settings please contact your script developer or your hosting provider or once try in config/config.php i couldn't see this file anywhere it maybe in ../common directory find it and check 

Thanks! I made it! Works!
