How do I manually upload the logo image and the .css file? Please help

I have tried all the ways to upload the logo image and the .css file and I have not been able to continue showing me the following message:

That’s why I want to know in which folder I should directly place the logo image and in what folder I should upload the .css file
Thank you

Hi @Pandora_ramin,

I see you’ve also posted this on another thread. Please don’t double-post; it clutters the forum.
