Well I checked your site and found that the server is returning 403 error and somehow blocking the access to popup.php file in vibe shortcodes plugin .
check screenshot :
http://prntscr.com/e30v8n
this is why there are no settings shown in the vibe shortcodes popup in backend .
Can you please share your server php error log to debug this further .
Please also contact your webhost for the 403 error.Also try deactivating third party related to security plugins and again check the issue .
