I see the :pencil: icon, and can modify the text, but there is no save button.
I have the default theme, with (an old version of) DiscoTOC - but I don’t think that’s the problem (is it?).
I’ve tried this, to no avail:
```plaintext
./launcher enter app
rails c
Discourse.clear_all_theme_cache!
```
and the console says:
```plaintext

I have user reports of other similar UI bugs since last update (to 3.6.0.beta1-dev), but this is the one I can also reproduce myself. Reproduced in Brave and Chrome.

Think I’ve worked it out. The date/place overlay from [Events Plugin 📅](https://meta.discourse.org/t/events-plugin/69776) must be hiding or overwriting the save/cancel buttons.
I’ll have to try an update.

OK, updating to latest version of Discourse and Events Plugin seems to have fixed this.
