Dear readers, dear Danny,
I have installed the plugin "Newsletter Sign Up", but for some reason I am unable to place that checkbox before the submit-button. It keeps showing up after the button, which does not look professional.
Yesterday, I found out that the theme I'm using is causing the problem. (Which is called zeeBizzCard, by the way.) I don't know exactly how to fix this. I do have a little knowledge of CSS, PHP and HTML.. and I figured out that it might have to do something with the css.
Hopefully someone could help me, because this plugin is great! (Petje af, Danny!)
Note: here you can see what it looks like.
