<h4>Upgrade from 0.1.x to 0.1.4</h4>
If you upgrade to 0.1.4 please run the “rebuild birthdys”-script. This because of changes in storing files on the system. 
 When using 0.1.6 and you changes an options the rebuild will be done for you.

For some reason there is 2 breakspaces in the wp-birthday-users.php at the end. Delete these to let the plugin work. (I try to fix it later)
