I have implemented a custom BBCode from this author: https://www.phpbb.com/customise/db/bbcode/new_spoiler
I just noticed that only one spoiler per reply works. If i add two spoilers per reply, each with different text, upon clicking the "show" button, always the first spoiler content opens.
If anyone got any idea how to fix this, it would be great
cause the author isn't reacting to any questions.
