A few days ago I guess I was not alone in receiving this from Lunarpages:
This email is regarding the outdated installation of certain PHP scripts you have installed on your account. For security reasons you must update these outdated installations as soon as possible. In the event that they are not updated within 5 business days, they will be automatically updated. Please keep in mind that if your scripts are automatically updated, you will run the risk of something on your site breaking.
We strongly recommend making backups of your site’s content and any custom settings you may have. If you do not create your own backup, you run the risk of having to recreate content or your entire website. However, in the event that you do not have your own backups, our system keeps backups for 3-5 days. Please understand that we will not restore your account to any date prior to the updates made. Any accessible backups will be zipped up and made available to you to download locally. We will not allow any rollbacks or restores to previous versions. These backups can be accessed through our Managed Shared Hosting program if you need them.
The following script updates are available:
My immediate concern is for my two MediaWiki installations, both of which are v1.29. These are going to be compulsorily updated to v1.30. I have already tried the update myself and it fails every time because FileInfo needs to be enabled. I have talked to the support team about this and they steadfastly maintain that FileInfo will not be enabled on shared servers (such as Elara) because it will take up too many resources. They also suggested that I keep a local copy of a backup - but, of course, if MediaWiki 1.30 doesn't work there will be nowhere to restore it to, so
Bottom line is, when the upgrade goes ahead, my two wikis will stop working so I would like to stay at 1.29 until either Lunarpages can work something out re FileInfo, or I can come up with an alternative plan. Preferably the former, but if I have to move to another hosting company I would like the time to do some research first and will also need to work out how to export (not just back up) my wikis, which isn't at all straightforward.
