SSL gets unencrypted when I access Slideshow CK

ok,
2/ for the blue color this is because it is a link, and the link color is taken from your template. You can change this by adding this into a css file
3/ if you want to link something on the image, you must set it in the "link options", not in the video options of the slide

4/ + 5/ have I something to answer on this ? I don't really understand the request here

but I see that you have the title twice in the caption, are you using an article and setting a title in the slide field ?

Hello Mr. Ced,
Thanks massively for your response here.

By your answers here, I think I am getting there except maybe, with the video bit. But hopefully, I know everything will be ok.

With the 4/ and 5/, I added them so that they could probably serve as a clue if I was doing anything wrong.

Thanks once again for your help.
