The enablement of Elxis SEO PRO is a piece of cake! Go to global configuration and under the SEO tab select "SEO PRO" as the SEO mechanism to use. In your Elxis root folder there is a file called htaccess.txt. Open this file and set the proper value for the RewriteBase (if Elxis is in your www root folder then it should be just a slash "/" ). Rename this file to .htaccess. Thats it! Notice that Elxis SEO PRO can also be used under the IIS webserver. In this case IIS should be equiped with Ionic Isapi Re-writter filter.
