Hi mace0ace,

To solve the issue related to quotes use the following CSS code, put it in Dashboard > Forum > Settings > Styles > Custom CSS Code. 

blockquote p:before {
   content: "" !important;
}

The problem with images has no relation to wpForo. Have you migrated from another forum?  

Please try to execute this SQLs in Hosting Service cPanlel > phpMyAdmin > WP Database > SQL tab, it should solve the issue.

UPDATE `wp_wpforo_posts` SET `body` = REPLACE(`body`, 'https://jyxo.info', '//jyxo.info');

If the table prefix is not wp_ change it before executing.

Please backup the database before this manipulation.

thank you, it will take some time.
I do not know about migrating from another forum, but the images may appear if we remove them from the link: "https: //" - will be tested.

video links youtube do not create previews, this issue will be resolved?

Thank you

the quote problem is resolved, but the code needed to be placed elsewhere - Appearance, editor, CSS editor  thanks
problem with pictures is solved
The last question is: Can we instead of a link to youtube videos, show thumbnails?

You can display Youtube video instead of link if you use the custom code mentioned here:

For other video embedding options I recommend wpForo Embeds addon:

it's not a custom code, it's a link to a post in a forum with youtube video
