Hello again!

Today I finally published the web and I have several problems that I do not understand why it happens; since I did everything following the tutorials and consultations that I did through the forum. The problem is that when I see the web internally, the web looks perfect, if there is no problem, but when I publish it, not all the real changes appear.

At first I have problems with the logo; either in SVG or PNG format.
Along with this I have problems with the classes created by imported fonts.
I have seen that I have several problems in the html with the vimeo <iframes> and little by little I will correct them.
I attach the link to my website: manugonzalez.net and a video where I show the problem I comment
