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

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.

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.

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

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

Is it true that this might be caused due to similar body content, as mentioned here,
> **[500s and "Body is too similar to what you recently posted" errors](https://discourse.mozilla.org/t/500s-and-body-is-too-similar-to-what-you-recently-posted-errors/8591)**
>
> When posting, I sometimes get a “500” error and then the message “Body is too similar to what you recently posted” when I retry. Nothing is successfully posted in such cases.
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

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.
