My users come in at trust level 1, so they should have all basic user functions, correct?
But they can’t create posts. Am I missing something?
i’ve looked at other 500/internal server error posts in ‘support’, but haven’t found anything i can translate into “what next”.
Thanks.
This kind of thing should show up in /logs, what do you see there?
nothing that i can interpret. can i copy that into here?
Yup, be sure to look at all three tabs at the bottom and redactv sensitive info.
Info tab:

That’s an old version of Discourse, can you upgrade to latest?
nope. that’s in the hands of Discourse Hosting.
is it very old?
We moved to Ruby 2.4 in Oct 11, 2017.
then i’ll contact Richard. will that solve the issue?
To be honest, I don’t think that the Ruby version is the issue here. This is happening inside Redis and it’s on a large multisite installation where the error is only happening with this forum.
This must be something in data that is specific to this forum or category.
Update:
The site setting max_topics_per_day was set to zero which was causing this problem.
This site is running version 1.9.5-something (which is not an “old” version of Discourse, only two days old)
This bug is fixed already but the fix is not backported to stable.
