Article Publisher PRO v2.2.0 installation of seo friendly url in justhost server the script is already installed all i want is to activate the SEO friendly urls which is not working for example: [login to view URL] gets redirected to error 404 page something in .htaccess file needs to be done that is: ---- The Search Engine Optimized URL option requires support of .htaccess files. Your server must be able to execute .htaccess files. This file is located in the /_extras/ directory. .htaccess files only work on Apache web servers. ******************* Our support only includes allowing you to download updates to the script and us addressing any reported bugs in it. It does not include personalized updating of any site. The problem is likely to be the .htaccess file, which is SERVER SPECIFIC. When the SEO URL option is turned on, it is what rewrites/redirects page requests. It may require some change for the precise way your server is now configured but, again, that is not actually the script, it is server-dependent. See the installation instructions for more notes, or just look for the .htaccess file in the main script directory. *******************
