Your 'current' license key does not match your valid key, please license your vBSEO instance by saving your valid key as your 'current' license key.

where i make mistake

Hello ,

On each vBSEO version license key changes. You must make sure you copied your newly supplied license key and save that key. Prior saving your license key please make sure your config_vbseo.php or config.xml files are chmod 666
