.htaccess and the 404 redirection

Hello, last week I edited the .htacces on the htdocs file. About 2 days ago every link of my page is going to the infinityfree 404 page. I can see that my .htaccess is not on the .htdocs file anymore, and when I tried to upload another .htdocs file it just disappear one second later. What can I do now?

Hi,
I am confused about the file you called .htdocs.
Could you please provide a screenshot of the file/folder?

@chatojavier your .htaccess file must be less than 10 kB in size

Ok, probably I have to erase 7/8 of the document.
