System Setup HTTP 406 Error

[topcat24]

Is this happening on a test computer, or on a live webserver?
Who's the host?
Can you share a URL to the zc_install folder?

I have sent you a pm with all the details hopefully you may come up with answers. It is a live webserver

Your server's mod_security or related configuration is blocking the passing of "http://..." in the browser URL.

This is a known problem affecting a small percentage of hosts, and a workaround is being developed for v1.4.0.
In the meantime, the best solution is to ensure that your zc_install/.htaccess file contains the directives to disable mod_security.

The default contents are:

# The following disables mod_security in apache, which may be necessary during installation
# This file should only be used INSIDE the zc_install folder. Using the following directive elsewhere can
# cause security problems on your site. Talk to your webhost if you are concerned about its effects.

<IfModule mod_security.c>
    SecFilterEngine Off
    SecFilterScanPOST Off
</IfModule>

## If for some reason the above doesn't produce the desired results, simply remove the # from the 
## following lines:
#SecFilterEngine off
#SecFilterScanPOST Off

You could try changing it to just read this:

SecFilterEngine off
SecFilterScanPOST Off

Granted, if your host doesn't want you to override it, then using this method will cause a 500 error.

I tried the change to the .htaccess but I got the 500 error so I guess I will have to wait for the fix or change host

... or ask your host for a way to disable mod_security for 5 minutes ...

I was able to manually install it (not the best way but it works ok at the moment) but next time i have to upgrade I will ask the hosts to disable the mod_security for a short time, thanks for your help
