After some security issues with the CMS system that powers this webpage, it was necessary to upgrade the system.
The upgrade was started on January, 28th, 22:00 GMT+1 and finished at 22:19 GMT+1. During that time there have been some slight inconviniences using the pages. Now the pages are up and running again.
Thank you for your understanding.
