White page

Well i ftp everything in the upload folder corretly, but i dont really know what is the htaccess folder is for and what it does. I see alot of rewrites or something and i dont know what it's about as well

I imported the xml file from do not upload folder from my acp, and then my forum gets a white page, right now, i deleted all the files from the ftp so that people can go back to my forum, so what should i do? I really want to install this but somehow im having some problems : /

You should upload the .htaccess file to your forum root folder in BINARY mode. If you already have an .htaccess file, simply append the rewrite rules included within the vBSEO .htaccess file to your existing .htaccess file.
