I currently use Drupal 7.5.3 and need to upgrade to 7.5.4. Running it with CiviCRM. I'm a novice with this site and need a little hand holding to figure this out. Basically the site admin is AWOL and the person running the organization I'm working for asked me to figure this out.
I used instructions from here: https://wiki.civicrm.org/confluence/display/CRMDOC/Upgrading+CiviCRM+for+Drupal+7#UpgradingCiviCRMforDrupal7-1.DownloadthemostrecentCiviCRMPackage
I'm stuck at steps 7 through 11, since I don't know where the code files are stored or how to access them.
