I'm building an internal wiki on my company's intranet. Here's our setup:

MediaWiki - v1.17.0

PHP - v5.2.17 (cgi-fcgi)

MySQL - v5.1.56

I can create a new page with up to three labelled external links, and everything works just fine. For example, this will work:

[http://google.com Google]
[http://yahoo.com Yahoo!]
[http://bing.com Bing]

However, as soon as I add a fourth link, I get a "403 Forbidden" error whenever I try to save the page. So, for example, this will not work:

[http://google.com Google]
[http://yahoo.com Yahoo!]
[http://bing.com Bing]
[http://msn.com MSN]

If the fourth link is enclosed in square brackets without a label (i.e. [http://msn.com]), I also get the 403 error. However, if I simply put in the fourth link as a URL without any brackets (http://msn.com) then I can save the page.

The full text of the 403 error is:

Forbidden
You don't have permission to access /wiki/index.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

What would cause this behavior? Is there a setting that limits the number of labeled, external links I can put on a single page?

Thanks in advance! I appreciate any advice or insight.

Does your Apache have mod_security?

No, I don't think so. I created a page with "phpinfo()", and it did not contain any mention of mod_security.

Hello, I also have this problem. How do I add more than 3 links to my Wiki's linkpage without getting this error? Is it a bug or a feature I have to turn off?

Thanks in advance!

This is caused by mod_security.

See: Thread:Project:Support_desk/Page_wont_save_with_cimetidine and bugzilla:51323.

Ask your hosting to turn it off.
