There is several ways to custom css.
most simplest is adding in to your theme css.

can you post your website link?

of course it’s possible. You just need css and html knowledge.

html:

<div class="youtube">
[youtube embed code]
</div>

css :

.youtube {
background: url('location/your-picture.jpg');
padding: 15px; /*change with number pixel you want*/
}

By looking your page source, for quick fix use this code in your widget:

<br><br><a href="https://csolberg.getwwn.com" target="_blank"><img src="https://www.myelitehub.com/assets/images/banners/wwn/250x250-C.jpg" width="250" height="250" border="0" style="margin-left: 25px;"></a>

and

<br><br><a href="https://csolberg.thecopywritersguild.com" target="_blank" style="margin-left: 25px;"><img src="https://www.myelitehub.com/assets/images/banners/cwg/250x250-B.gif" width="250" height="250" border="0"></a>

it’s added with style=”margin-left: 25px;”.

Hope it’s help.

Are you familiar with MySQL with phpmyadmin?

If not, you should see https://support.godaddy.com/help/article/5942/accessing-phpmyadmin-on-your-shared-hosting-account how to get there..

Then by this tutorial: https://www.youtube.com/watch?v=2P_iaiw1III start from 7:17 browse your wp_comment and check is there any saved data of previous comments still in there?
If you still have the wp_comment data, you can try to reinstall wordpress by backup all your files and database first.

Have you tried change your themes?
If it work with default wordpress theme, it can be not compatible with your current theme.

or maybe

Check your database via phpMyAdmin (most hosting providers offer this in their control panel), do you have an wp_comments table?

While you’re in there, also check all of the tables and choose “Repair Tables” from the bulk actions menu.

I see in your website Page Source all link using ipaddress https://54.xxx.xx.xx
Did you install wordpress from ipaddress? you should install wordpress from domain name.

to fix current problem.. you should check your wp-config.php if any written https://54.xxx.xx.xx change it manually to https://www.net2tel.com.br

also in phpmyadmin.. go to your database wp_options change siteurl and home to https://www.net2tel.com.br

in browser console log got error:
Font from origin 'https://54.xxx.xx.xx' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://www.net2tel.com.br' is therefore not allowed access.

Try to change the link to load the font using domain name https://www.net2tel.com.br/ instead using ipaddress.
