Drupal website developers and administrators benefit from its built-in feature to periodically check if any of the enabled modules and themes are out of date. Drupal performs this check daily or weekly, when its cron job is run, automatically. If there are any modules or themes in need of an update, then on the admin area's modules or themes "List" page, you will see the notification:

Every so often, when migrating Drupal sites to other computers, I notice that themes become disabled. Whatever the cause, disabled themes cause bunches of problems, and my big problem today happens to be with Skinr.

If you are trying to edit settings in Skinr, for example settings on a block, Skinr only shows you those options based on the currently enabled themes.

To get the Skinr block settings fieldset back, visit your admin/build/themes page and make sure at least one theme (like your default theme) is enabled.

Ever downloaded a module and noticed several obvious bugs? Often, you can look in the issue queue for a module and find fixes, code patches, and help with these problems. For certain modules, the maintainer of the code may not respond - he or she may no longer be developing with Drupal, may have changed his or her email address, or any number of other factors.
