Retake Quiz Button not working

Hello,

Most probably this is a caching issue, your page is cached. please follow these steps

1. Please deactivate all installed 3rd party plugins.
2. Delete browsers cache especially cache plugin.
3. if any extra codes added by you then remove it.
4. Re-save permalinks.

if it does not work only then let me know.

hello,

Please share wp-admin url and credentials with ftp connection. I need to check this on your site.

i will also need the url of the course and quiz.

---

if you are playing with the codes then i can't help because i don't know where have you made changes or what have you done. it will be a tedious work to debug then.
