If your posts are redirecting to the homepage the most likely cause is your posts are actually 404 error pages, however you have enabled redirection for 404 pages under Theme Panel > 404 Page.
Step 1: Disable 404 Redirections
First disable this option then try accessing a post again to see if it is redirecting or displaying the 404 error page.
Step 2: Re-Save Permalinks
If your site is displaying 404 error pages for your posts, go to Settings > Permalinks and click the save button. It normally fixes permalink issues on your site. If it does not, you may have to update your .htaccess file manually. This is a server issue and it’s outside the scope of the theme and theme support. If you still can’t get things working after re-saving your permalinks you should try contacting your webhost for some help.
