XF 1.5 The following error occurred: Not Acceptable An appropriate representation of the requested resourc

We're getting a really odd error for some threads (not all).

The following error occurred:
Not Acceptable
An appropriate representation of the requested resource /threads/ftp-thread.40998/add-reply could not be found on this server.


Screenshot:


It's like this for any action on the thread (edit, delete, sticky, etc.)

It happened on an old thread initially that had come across from our phpBB3 board. So I thought maybe it was a bad conversion or something.

So we set up a new thread about our FTP details and the same has happened again.

Other threads in the same node still all work absolutely fine (and setting up new topics works too).

Is it anything to do with the fact the thread has FTP in the title?

This is likely due to mod security on the server.

Contact your host and they should be able to whitelist for the rule which is being triggered, or disable it.
