1 May 2020 the site was compromised and defaced. WordPress, even without any special plugins, apparently remains vulnerable.
For years my webpage was hosted at VlexoFree. For free, as it was only a personal website and project on the side, it did not get much attention.
In march 2019 VlexoFree announced to retire, after 10 years of flawless service.
I decided to take this opportunity and upgrade my web presence to more modern times. The old one used a CMS (CMS Made Simple) from 2011. Which is stoneage in the world of the internet.
Today, this website is now hosted at Versio, with WordPress, which should hopefully lower the threshold of placing something online.
