Thanks Yann! That is exactly helpful! Managed to resize correctly all post videos without any plugin at all with just a few lines of code.

If you don’t mind, would be good if you can point in the direction where one may learn these WordPress tricks. I googled but didn’t help.

Yes. Can you advise how?

Thanks Yann.

I am not sure if too many tags and links are applied to the posts. Will it have an adverse effect on SEO or Google search results?

Perhaps I can undo or reduce the auto terms and links applied?

Thank you.

Thanks CrouchingBruin.

Yes Appearance -> Customize Hangs.

But I found out the problem after I paid for a fiverr fix. It was just one of the plugin that caused this problem.

Nice day!
