I could not find them.
You might need to activate one of the composers. The default composer should be activated, but perhaps it got deactivated by you? Give that a check.
We say by and large that NodeBB doesn't run on shared hosting, but that is an oversimplification. Most do not, since they are geared toward php applications that you drag and drop files into via sftp.
If your shared hosting provider gives you shell access to install programs (namely mongo and nodejs), then you should be fine.
@anmol-gupta Just activate the new theme from ACP
@ChaosYamYT This plugin is incompatible with current versions of NodeBB. You could try opening an issue at the Github repo for the plugin, and asking the developer to fix it.
That worked. Thank you.
