Error message while posting

Hi everyone! I am currently posting a rebuttal to a Heritage Foundation article and whenever I press post, I keep on receiving this error message, rendering it impossible for me to post:

As I ain't a tech savvy guy, I don't know what error occurred. Do any of you have any suggestions on how to fix this?

Here's what I would try:
1. Copy your text to a text editor and save it as a general precaution.
2. Let the browser reload the page, then try again (if you are still shown as logged in).
3. If that did not work, try to post only a part of your text at first, and then extend it by editing the post. You may be able to narrow down which part produces the error that way.
