IPI’s website has been hacked. This was only noticed today, no way of knowing since when this has happened.
SOLUTION/ WORDPRESS/ FIX THE HACK/
Some useful notes here.
Likely that the problem will go away by restoring an older wordpress database (found in cpanel> database backup).
Unfortunately, the hack was older than the last available database backup.
Finally, I was able to restore the site by copying code from archive.org where a copy of a December 2016 version of the site was available.
