500 Error While Posting a Topic

Bug
1

I get a 500 Error while trying to post a new Topic. I am the Admin and have posted and am able to post multiple other topics. But, only few set of topics are throwing me an error.
Title:
Why should I learn computer programming even though I am a commerce student? How can computer programming help me?

Could someone help me understand what could possible go wrong here

2

It could be you topic character limit. You might be exceeding the limit

3

Hi @IAmGav,

I have kept the topic character limit to the maximum.
I have increase the max post length to 150000.
Max Topic Title Length to 255.
Title max word length to 2000000000
Any other possible reason.

4

The Number of 500 Errors have been increasing considerably. Not able to identify the exact reason. This is severely affecting my forum. Could you someone please help me here.

5

I went ahead and took your article and posted it on one of my discourse server without even touching any limits.

It posted fine.

You might want to look at your server errors.

This is not a discourse related error

6

Thank You Gavin.
Not sure why all of a sudden this has started to happen

7

Visit the /logs page on your forum and check for errors.

8

/logs page does not exist in the domain. (mpl.co/logs)
Could you please help me understand how to access.

9

You must be logged in as the forum admin.

10

I am a forum Admin. Do we have to configure it?

11

Is it true that this might be caused due to similar body content, as mentioned here,

If yes, how to disable this feature. I’m comfortable having a Check for duplicate titles. But, I don’t want Discourse to throw and error for similar body

12

you could try these

We can not really help much without seeing the /logs visit YOURSITENAME.COM/logs after triggering the issue, copy the error you get and paste it here.
