I have something else, and it works perfectly (please see: https://www.klifix.nl/ for an example) it isn’t a wp plugin, but I just downloaded it somewhere.
you might need to reset your database, because in there is your username and pasword stored.
When installation is done you won’t get a pasword emailed to you, it is directly visible after installation. So I guess you didn’t saw that and waited for the email. You can get your pasword out of your database (PHPmyadmin).
I need to tell there is no single.php file in the theme folder, is that a problem. And will the news noty show up in the sidebar.php if I insert the code in there?
Cool blog, nice lay-out, altough it’s not really my kinda style, it’s a little bit boring. I’m not really into PHP or other programming so I wont say anything about that, but everything works fine as far as I can see, so keep up the good work!
