"Category does not exist"/Composer problems

[Shelby D. Avila]

I have a redactor composer plugin on my forum and it looks great and works perfectly when replying or in chat but when I try to actually make a new thread/post I get the error "Category does not exist".

I'm an absolute normie with coding or any of this stuff and I'm doing my best to troubleshoot setting this thing up. Any help would be greatly appreciated.

This is the plugin
https://github.com/NodeBB-Community/nodebb-plugin-composer-redactor#readme

This is the tutorial I used to install nodebb initially

install nodebb ubuntu 18.04 With Cloudflare SSL

Additionally I can't seem to get any other composer to work properly. Even the default composer plugins. Usually they will only work to post text alone but not even the preview function works. I'd love to have a redactor composer but at this point I'd probably take any basic composer if it would work.

Thanks for any help in advance!
