Error 500 posting a simple post

[x1800]

One of my user has this weird problem.

WHen he cut n paste this text

"No. That is up to the ISP anyway, you should NOT emulate a
TFTP server on your machine... that is a big No-No, and in fact, it is forbidden
in the DOCSIS specs. It is true, however, that you can trigger the modem to accept
a TFTP server over from the NIC side, unlike what it has to be, from the HFC side only... :wink:"

into the vbuletin forum 3.6.7, the server will throw an error 500.
Other posts seems ok. What would be wrong?

A http 500 error is a "internal server error". You will need to inspect the webserver logs to find the cause.

A common cause for this is a malformed .htaccess file or Suhosin/Hardened PHP.
