Linked my blog to prestashop failed

[hallen77]

Hi,

 

I've added a link in my blog navigation bar pointing to my prestashop. When I click on this new link, the page changes color, then my prestashop index page tried to be displayed ... but the page is a mess.

If I right click on the link and open it in another window, prestashop index page is diplayed successfully.

 

The problem appears only on the blog navigation bar and on the blog sidebar, and only when the link is pointing to my prestashop.

 

If you want to see, here is my blog www.dietetiquetuina.fr, click on the word "Boutique" on the navigation bar (the last one)

 

 

Any suggestions ?
