I face with a strange problem yesterday. I have server running Debian with installed PHP 4.4.4-8 and mysql 5.5.9. That server serves a several websites. For some reason randomly I get that error "Access denied for user www-data @ localhost (using password: NO)" when I try to load the webpage. If I hit refresh the page loads normally, but afer several clicks that message appears again. Username which that page use to connect to mysql server is not www-data.
是否有任何人面临同样的问题?
