Adding SSL certificate to the front end of my site

I use https://wordpress.org/plugins/force-ssl/ and https://wordpress.org/plugins/http-https-remover/ This ensures that if I go to an http page I get redirected to https and that everything like images is requested over HTTPS.

Hata!: SQLSTATE[HY000] [1045] Access denied for user 'divattrend_liink'@'localhost' (using password: YES)
