Hi there, I just took a look at your site and I like what you did. Unfortunately, the theme isn’t coded so that the header image is linked to the home page. It’s meant to have a title and description. However there is a way around that. It does take a bit of coding, but it’s pretty easy.
The first thing you’ll want to do is make a child theme.
Once you have a child theme, you should have a folder (call it mon-cahier-child or whatever you want). That folder will have a style.css with the following info in it.
Theme Name: Mon Cahier Child
Description: Child theme for the mon cahier theme
Author: Your name here
Next you want to open the parent theme (mon-cahier) and copy the header. php. Bring that entire file in your child theme. Open it in a text-editor and on line #39, you can edit the line like so:
That’s it. Once you are done that, you might also want to install a plugin like WordPress SEO. Because you’ve removed the site title and description, your page titles now are not very informative. Just a thought..
