I have updated my site and my site is still being blocked from outside traffic. Please use the following the steps.
Please make sure that there is no other old Drupal Installation(s) on your site.
Here is how to find out if you have other installation(s) on your site.
1. Search for your site on the Restricted to campus only network site list. You also will be able to find this link on your Plesk Web Admin page on hosting.gatech.edu site here (image below). You can see how many Drupal Installation(s) you have based on your site's name. This list also provides you the path of your installation and it's version.
2. If there is other installation(s) in your site. And if it is not 7.58, nor 8.51, you will need to either uninstall that installation, or update that installation to be 7.58 or 8.51 based on your current version.
If you have done all the following…
- I have updated my main site to version 7.58, or 8.5.1.
- I do not have other old Drupal installation(s) on my site, or I have updated other Drupal installation(s) on my site to version 7.58, or 8.5.1, or I have removed other old installation(s) that I don't need.
Then…. Please check on the followings notes.
- Cyber Security has an automate process to release updated sites (version 7.58, or 8.5.1) routinely.
- If you know all installations on your site have been updated and your site is still blocked over 12 hrs, contact support at firstname.lastname@example.org.
How about Drupal 6? If my site is still using Drupal 6?
Drupal 6 is End of Life and all Drupal 6 sites will be blocked. The block will be released upon upgrade to Drupal 7. However, please be aware that this is considered as a major update. Make sure to backup your site before this upgrade. And if the upgrade is not possible for your site, you might need to consider rebuilding the site. Here is a resource on how you can migrate your Drupal 6 to Drupal 7. https://drupal.gatech.edu/handbook/migrating-drupal-7-drupal-6
