Marketo form does not appear on some Wordpress pages

[an6]

Hello. On our WordPress blog, we've created a Newsletter subscription pop up linked to a Marketo form. When someone arrives on our blog, the pop up appears and the visitor can register by filing out the form in the pop up. It works perfectly on our home page (https://blog.dys.com/) but the form does not appear in the pop up on any other pages of the blog. To be more clear, the pop up appears but without the form. 

Under WordPress, the pop us is sets up to appears on all pages. Under Marketo, there is no rules implying that the form should behave differently on other pages. For now, we can't really understand where the problem come from...

Did anyone already experienced this kind of issue? 

Thanks for your help.

I can’t reproduce what you’ve described. As long as the cookie spu_closing_943 is not set to true (which happens when you close or click outside the popup) the popup is visible. Here it is on one of your inner pages:
