403 errors

I'm getting 406 errors on my site. What might cause this and how do I fix it? Thanks

I looked it up and found

A client (e.g. your Web browser or our CheckUpDown robot) can indicate to the Web server characteristics of the data it will accept back from the Web server. This is done using 'accept headers' of the following types:

* Accept: The MIME types accepted by the client. For example, a browser may only accept back types of data (HTML files, GIF files etc.) it knows how to process.
* Accept-Charset: The character sets accepted by the client.
* Accept-Encoding: The data encoding accepted by the client e.g. the file formats it understands.
* Accept-Language: The natural languages (English, German etc.) accepted by the client.
* Accept-Ranges: Whether the client accepts ranges of bytes from the resource i.e. a portion of the resource.

If the Web server detects that the data it wants to return is not acceptable to the client, it returns a header containing the 406 error code.

So when I click a link in the Physics module for Quantum Mechanics I get a 406 but not when I click Unified Field Theories... why?

406 errors are errors related to mod_security rules. They are defines at the server level. Please email to me the link that is returning the 406 error and I can then tell you why and if it is a legitimate link then I will need to make a tweak to the rule.

OK I'll email it to you.

I have tweaked the rule set so you should be clear now.

It is clear now, no more 406 errors. Thanks very much Smile
