Cannot Post to Discourse instance, Published Category does not Display in settings

Hi all,

I’m receiving a number of different errors as per the logs depending on which page I’m on as per the following:

Posting a post:

For some reason, I have a feeling that this may be linked to the way I have my wordpress/discourse configured in nginx, but who knows, I could be wrong on that front. For reference, I’m using a setup similar to this: Nginx + discourse - #6 by wesochuck. This is also a similar problem: https://meta.discourse.org/t/wp-discourse-dysfunctional-shows-only-start-the-discussion-at/36016/4, but none of the suggestions there seemed to have helped with my case.

Discourse settings:
Discourse URL
Full url is set properly (http:// discourse.josiahtoppin.com (that space isn’t there, I can only post two links here as for being a new user)
API Key


Publishing username
Josiah.Toppin

I’ve regenerated the api key a number of times and have also ensured that the user posting the post has the correct Discourse username setup in the discourse environment. I’m at a bit of a brick wall at this point.

SSO is working properly using the separate plugin. SSO using this plugin seemed to break things.

Hello everyone; I’ve played around with a few different nginx configurations and that hasn’t helped. I’ve taken a look at the firewall rules I have set up and that doesn’t seem to be an issue, but I’m not an expert when it comes to iptables. I will do a bit more testing and see if I can’t resolve. For some reason, I think it might be related to my firewall, but I can’t be sure.

With fastcgi errors might want to check you php.ini settings. Do you have
furlopen set to 1? Also I noticed it’s trying to open both
www.josiahtoppin.com and josiahtoppin.com. Do you have DNS setup for the
non-www address or are you doing a rewrite rule?

Just tying to think of things to check.

Do you use easy engine btw?

I am using easy engine. I was about to jump in and try the other advice until I saw that you mentioned that and thought it would be pertinent to mention before delving deeper into this issue. @Grex315 I’m still learning discourse; do I need to mention people in replies?

Edit: Furl is on and dns is setup for the non-www address - www is added via wordpress site address.

nah. dont think Easy engine would cause an issue just recognized the path setup. I use EE as well but just so i can get their NGINX repo. They have all the modules I want already built in. The rest I setup myself.

Have you try disabiling all other plugins.and just have this one going to see if there is a conflict? Also in the plug in settings for the category drop down is it showing a populated list of categories or is it blank? That would tell you if your API key is working and the plugin is connecting to your discourse instance,

Hmm. No joy on disabling plugins - still no go.

Nope, drop down is blank, so it is definitely not connecting.

Played around with some temp firewall rules and nothing seemed to do the trick. I’m at a bit of a wall here. I posted it over at rtcamp and opened an issue up on github in the mean time though.

Well. Good news and bad news.

Good news is I got it working through the embeddable settings with an RSS feed and using this: https://github.com/techAPJ/wp-discourse-embed plugin.

Bad news is I had to ditch the regular wp-discourse plugin for now.

Now if only I can figure out why the topics aren’t being posted to the specified category in my embeddable settings. That is for another topic though.

Ok. Glad you got something to work.

I was going to suggest was using and admin account or just putting system
in as the username creating the posts.
