ok
Got a 406 error today when I was editing a product
Forum didn't have a huge amount of help on the subject so I thought I post what I have been able to find out / do
Got hold of my host and for once they were quite helpful
Still need to look at why it does it but the htaccess thing fixed it
Following the spate of outages a couple of weeks ago, the server techs installed the apache mod_security module. It is essentially a webserver-level firewall.
It shouldn't have caused any problems, but it could interpret some actions as bad, typically POSTs containing what it considers dodgy data.
I have found a way of disabling mod_security. Just place the following in an .htaccess file in the directory containing the script file:
SecFilterEngine Off
