Hello, After upgrade the dicource, the plugin of Automatic TOC was disappear all topics. Could you advise to fix it of theme “Horizon”?

@bck055 I think I know what the problem is. Nested replies enabled causes the TOC to not show up. Normal topic with TOC: [image] With nested replies enabled: [image] I suggest you disable nested replies on the affected topics and try again. Admin wrench > Disable nested replies. [image]

DiscoTOC is not a plugin, but a Theme Component. Is it currently installed at /admin/config/customize/components? If it is, could you send a screenshot of what you’re seeing? If not, install the plugin by clicking this: Install the DiscoTOC theme component

Installed but not appeared. Do you have any ideas?

Odd. Does it work on other themes? Or does it only fail on Horizon?

Yes, after change theme and un appear

So the TOC only disappears on the Horizon theme, but works on other themes? That’s odd. I cannot reproduce this behaviour here on Meta. Can you send the link to your forum if possible? Or a screenshot of this problem? Thanks.

Nice Thanks for your support and fixed the issue.

غريب. هل يعمل مع سيمات أخرى؟ أم أنه يفشل فقط مع سيم هورايزون؟
