It seems I have solved the problem. I did stopping NodeBB then installing NVM, then installing latest Node (18.4.0 against 16.x.x before), and running "./nodebb build".
After restartng NodeBB works fine vith the plugin-searching.

Thank you very much for your time and participation, dear @PitaJ

@PitaJ, Nothing. Neither on the panel for plugins, nor in the browser console - nothing changes.

@PitaJ Yes, I can't this. I have the problem with the "find plugins" tab only. Sorry I didn't phrase the question accurately.

@PitaJ, when switching the tabs, absolutely nothing happens in the console:

here I try to install the nodebb-plugin-poll plugin:

@PitaJ, I don't know... that's all the console contains at that moment:

@kadmy anything in your browser log?

Please look at our chat where I placed the link to my HAR file.

@kadmy any errors in the server logs?

When I load "/admin/extend/plugins#download" no errors occur, neither in syslog, nor in dmseg, nor in journalctl

Here is nodebb.log:

What other errors could I try to find and where?

@crazycells Yes, exactly the same problem! "The plugin listing appears for a short time (≈0.1sec) and then instantly disappears"

./nodebb upgrade

I did upgrading (got two warnings: in entrypoint size limit and asset size limit). But there is no result: the list is empty.

by the way:

Hello dear @manolino, and thank you very much. Your plugin is realy useful for me - who is taking the first steps in NodeBB.

Let me ask you a question (one for now )

From Settings I turn on Paginator and Controls for slider. But they don't look too pretty. How can I style them?

3. Modify the Page template from Extend->Widgets:
   

4. Save, and voila:
