Update your Drupal to the latest version: 6.26 or 7.15
If, like me, you were busy before the summer and disconnected for a few weeks, you will notice that now that things are getting back to normal (kids back in school, vacations are over), you have tons of things to do at work and at home. In addition, to everything else, it also means updating all your devices’ OS versions with patches, your software applications and, of course, your own web based applications.
For Drupal, don’t forget to update your version:
