Hi There @artistn8
Thanks for writing in! I have checked websites assigned to this Themeco license and I see that you're using older version of Pro theme.
You can see the latest version and update information from here (https://theme.co/changelog/) and update your sites accordingly (https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62).
Further I would suggest you to regenerate your .htaccess file by head over to Settings -> Permalinks section, then selecting the option
postname and saving the changes.
If you're using a caching plugin on your server, you need to purge server cache after updating your Pro theme and also clear browser cache before testing.
Hope that helps.
