Shortcodes not working like before

Hello,
I have this plugin for years now, I didn’t update it until my site stopped showing, I had old spoiler, now its su_spoiler.

But I notice that even after update and search/replace of spoiler with su_spoiler, spoilers doesn’t open, tried to do tabs, not good either, …
Tabs all opened in the same time.

Overall some shortcodes do work, but most doesn’t. What should I do.
Link to the site is:

Where buttons work, but spoilers doesn’t!
Thanks.
