If I copy/paste to make a new thread here this is what I get :

406 Not Acceptable

An appropriate representation of the requested resource /forums2/post.php could not be found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.


However I can create threads without copy/pasted text.

Never seen that error before, but after looking into it a few minutes using my favorite search-engine...
Looks to be an issue with the web-server itself.

Seems that the webserver receives data it does not accept/expect.
On someone forum, someone said "I suggest you to install 'ConfigServer ModSecurity Control' and then disable rule 950004 for your domain."
For the user posting in question, that worked.

Perhaps your hosting provider can check their logs to see if they see something. What it is that the server does not accept/expect.

I don't see to have this issue on my server.
