@gav Ok, i do understand that you are not that familar with all that. So i'm gonna help a bit more, in the next few hours that i will have some spare time.

@gav Can you share here pls your my permalink structure? In Wordpress settings?

I'm using the Post Name option. The URLs show up as https.

Ok. The first thing you want to do is EDIT your pages so there are NO more http: in IMAGES links.

This is easy. It is your piano logo:

Change it to https:

Also this

 http://songwriterjunction.com/wp-content/uploads/2019/03/guitar-759353.jpg 

Change it to https:

An other one:

<h3 class="wpforo-forum-title"><a href=" http://songwriterjunction.com/community/announcements-suggestions/ ">Announcements &amp; Suggestions</a> </h3>

<h3 class="wpforo-forum-title"><a href=" http://songwriterjunction.com/community/whats-going-on/ ">What's going on?</a> </h3>

Just fix those and also every link with http:, there are many many. I can't find and post them all. There is a plugin to fix this, i don't remember what it is.

Also fix the menu to https: of my capture below.
