   login only with www following message is shown:

 * The landingpage of my website is just ok, but when I click the other sites via
   labtop or mobile it’s shown tons of hieroglyphics. I don’t want to post it here
   😉
 * Beneath yours, the cleantalk-plugin is also deactivated via ftp. Just added in
   the file name “…-temp”. Error still exists.
 * Don’t know if it’s now your business or like like it shown in the error message,
   revslider respectively cleantalk. Or should i push this post in another category?
 * Sincerly yours
