SSL checker status OK website NOK

[Edwin65]

I am using Plesk and installed for a few website a SSL certificate. When I check the SSL checker they show all info in green, everything looks good.

But when I check the url in my browser only two are working and show the green URL safety all the rest remain without the green.

Websites are on Wordpress
Domains are ;

villa133.nl
paarsekoemarketing.nl
mindmotivations.nl
hollandpromotiongroup.nl
fransvakantiehuistekoop.nl
vakantieparkchateaucazaleres.nl

My web server is (include version): OS ‪CentOS Linux 7.4.1708 (Core)‬
Product Plesk Onyx
Versie 17.0.17 Update #50, laatste update op 2018-04-24 03:24

My hosting provider, if applicable, is: Business Hosting

I can normally log in on my websites wit wp-admin

Hope someone can help me for this

I think part of the problem is based on the sites having mixed (https & http) content.
