Hello all, I run a small number of Wikis all using DokuWiki. For all of these, I am the only user (with two accounts, one with my name and one "admin" account). They are hosted by some of the large hosters with a good reputation.
This morning, I found that all visible pages on one of these Wikis had been deleted.
Not a big deal, I have of course a backup that I could quickly restore, but that leaves the question how this could be done.
A few observations:
- In the history of the page, the last entry was just "deleted", but without any information about the user who initiated the delete.
- Only "visible" pages were deleted, i.e. those that were also in the sidebar menu. The sidebars themselves were not touched, neither were a couple of pages that only contain redirections, short explanations or inlcude parts. Those were all still there.
Other instances were not affected, even one that is on the same server and has lots of cross-links.
Of course, I changed the passwords on all instances now, and try to find out more about the issue. I'll post it here as soon as I know more...
In the meantime, please be reminded to regularly make backups, and check access rights to all directories and namespaces.
