My host informed a few times that my site had a lot of malware. Although I tried to solve the problem by scanning my site, updating plugins, changing passwords and much more, the problem persisted. Over 15000 e-mails were sent from my site within 24 hours. Finally I decided to completely erase my site and start all over from scratch. It will take some time, but hopefully the result will be even better than before.
My new site will have the same basic structure: travel, portraits and male model images. I made a start on December 22, 2017. Hope it will be more or less ready within a month.
