Dear Discourse,

Whenever my post contains the word _substring_, an error 403 is displayed:

 ![AEA8ED8ADE2D46BFA0B1806DA242E04F](https://global.discourse-cdn.com/meta/original/3X/a/1/a13fb02bb43baae14bdffe556c1f9bc7b978b967.png)

For the time being, I just used _sub-string_ instead, but that’s not a workable solution.

You can [see my post here](https://ax.docentric.com/forum/t/how-to-capitalize-a-string/114/2). Is there any way to avoid this? I have tried to use all possible text formatting but nothing helps. Thank you!
