Inside newsletterpro.zip (sent upon purchase) you will see the folder "NewsletterPro". Inside that should be 2 more folders and a file named .htaccess. You can either extract the files to make them uploadable or copy and paste them somewhere on your computer. Then upload the folder "nladmin" to the main directory on your server. (ie: your-site.com/)
Now on you FTP software look for "ASCII" or "ASCII Mode." Switch to that mode. If you can't find it or it is not there then do as the next sentence says. Upload the folder "cgi-bin" to the main directory on your server. Every thing in it should upload automatically.
If you plan on using SEO (Search Engine Optimization) friendly URL's then also upload the .htaccess file to the main directory on your server, but do not upload it if there already is a file with that name. If the is then transfer the on on your server to your computer and open it in a text editor. Then add the following under "RewriteEngine On":
RewriteRule ^newsletters/([^/]+)\.html$ cgi-bin/newsletter/functions.cgi?action=$1
RewriteRule ^newsletters/archives/([0-9]+)\.html$ cgi-bin/newsletter/functions.cgi?action=archives&id=$1 |
