Hey, I don't have .htaccess on my wordpress blog but when I put it on the site goes completely down, which folder should I put it in? Regards, nut legend
some hosts have htdocs as the .htaccess file and some have public_html If your site doesn't have it and it works well, then there wont be any need for it. Or if you are editing it, you maybe replacing it by the old one via the File manager provided to you by the control panel of the host. Use FTP and edit it and see if everything is correct. I suppose the editing would be the main bit which will be causing this.
Is this solved yet? Put the .htaccess in your root folder and make sure you have the code needed for your particular permalink structure (you can see this in the wp dash settings>permalinks)
you might have inadvertently denied access to your whole site. check your .htaccess file against the standard wordpress .htaccess for permalinks. and yes, you need to upload to your wordpress default directory. i wrote an article on how to create .htaccess you might want to take a look.
if ur blog is in sub dir then look in that dir for .htaccess if it is in root then it will be in root dir. In linux/unix root dir name is public_html and in win its www. Sometimes this file is hidden. or u can create empty notepad > rename > .htaccess and upload > then edit ur codes.
