A problem with font in two different forums.

Hey, guys,
I have some strange problem that probably there is a problem IN the forum.

One of the installed fonts /I've put code in css/ is not working in the original forum.
Please, check this two screenshots from two different forumotion forums:






So, the first screenshot is from this forum: https://torenti.bulgarianforum.net/
The second it's from this - https://ezekiel-dynasty.forumotion.eu/

I would like to tell you some additional information:
Both forums I've open them from the same browser - Google Chrome and the same computer. So I can understand that the problem is from the second forum somehow, because if it was the problem in the font - it will not visual in both forums, right? The problem is not in the language, because I tried english and bulgarian and it's fine.
And one more thing - the first forum /Torenti/ is very old, created 2008 and I didn't make him "Encode your forum pages in UTF-8 now. "

So...
Please, help.

Hello

Are these two forums identical? Same templates , same css and same JavaScript?

Positive.
They have the same css /literally copied from one to another/ and templates as well. I don't have any javascript codes in the functions on.

can you click CTRL + f5 to the forum that the font is not applying

Nothing's happen, it is just refreshing the page.

can you delete the Platino font that seems to be installed on the second forum

No, nothing has changed.
I put 'President Cyr', arial
But there is nothing changed in the forum titles.

what is that platino font ?

It's font, but it's not installed in the css, I removed it from the forumtitle. Is it still there?

no its been removed

I tried to one widget "Welcome" upstair on the widget managment - https://ezekiel-dynasty.forumotion.eu/
Here.

But as I can see, the forum not recognise the font which is strange, because on the other forum - https://torenti.bulgarianforum.net/ there is not problem.
Right now, I put widget "Welcome" in Torenti forum and you can see there is fine.
I really don't know where is the problem...



Edit:
Okay, I think I found the problem...
There is three options in CSS section:
Force the basic CSS, Deactivate the basic CSS, Optimize your CSS...
I put all "no", the last one was "yes", but... I have a question - is it problem if everywhere is "no" ?

As far as i know this option just optimize the code might remove the unwanted white space and make the CSS load faster

My sets are no , no , yes

Yeah, mine too as well, but when I put no, no, yes, the font has been removed.
Now - 3x"no" it's fine, but I don't know is it good Optimised option to be "no" instead of "yes"?

Exactly how did you add it to your CSS?

I couldn't understand - add what? The font? If it's the font, check this part from my css code:

Code:

@font-face {
    font-family: 'President Cyr';
    font-style: normal;
    font-weight: 400;
    src: local('President Cyr'), local('PresidentCyr-Regular'),
        url(http://allfont.ru/cache/fonts/president-cyr_00ccedf9557cf1fa80208ea7f25ce7a6.woff) format('woff'),
        url(http://allfont.ru/cache/fonts/president-cyr_00ccedf9557cf1fa80208ea7f25ce7a6.ttf) format('truetype');
}
