[nodebb-plugin-soundcloud] SoundCloud embed plugin
Well, again: that's odd.
- visit the ACP and deactivate both soundcloud plugins
- restart nodeBB (click the little popup in upper right corner, after disabling plugins)
- wait for nodeBB to be up again
- enable only one of the soundcloud plugins.
If that still doesn't do the trick, you might want to update all plugins with the "update" button in the ACP. You have a lot warnings, regarding outdated plugins. If that again does nothing, my last two cents would be to deactivate those outdated plugins to see if they cause any trouble.
