Hello Anna,
Tranks for your reply, but please, check the page "yisy.ml" the page still working, but I deleted all folders included public_html.
I am thinking to remake the page, but now I can't...
I had an inssue with abantecart login page, so the admin of support page of abantecart told me that: You can try to remove all folders in the www/system/cache (please backup before do this) but login session is also stored in server folders not visible for you so you may need to ask your hosting...
