[Plugin: WordPress Social Login] 2 things to change

In plugin.settings.1.php please change ‘<%’ to ‘<?php’. same thing in plugin.settings.4.php.

Also, when accessing a wordpress table. Please do it like this :
$wpdb->prefix.’usermeta’
instead of
‘wp_usermeta’
because you have no warranty that wordpress use the default wp_.

continue your good work
