Question

I’m having this problem with a form, whenever I submit a form in this new server I get a 406 Error – Not Acceptable.

I only have access to the FTP of this server so any changes I have to made is limited by that.

I’ve checked if mod_security is enabled by doing this:

<IfModule mod_security.c>

... Perform some kind of redirect or re-writing in here ...

</IfModule>

It didn’t redirect so it means mod_security is not installed? If I run the redirect outside the IfModule tag it would redirect without any problem.

I’ve created a test form for you guys to test, just type in % on any field and click submit then it would display the error. Any alphabet character is okay and will not display the error.

Also I’ve added this in my htaccess file and the problem is still there.

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

What seems to be the problem here?

Edit: My original answer.

This is your problem.

You should look into sanitizing your data with the readily available
PHP functions. They can be found here, at PHP.net.

This SO question may help you as well.

Sanitizing strings to make them URL and filename safe?

Best of luck.

I was wayyy off the mark here. My apologies.

In your position, I would simply contact my webhost – they may not be allowing your .htaccess to override that specific directive. Additionally, since you’ve only got FTP access, it seems like you’d be dependent on them anyway.

Again, best of luck. Since it isn’t your webserver, you’re at the mercy of your host.
