problem with displaying 404 (error_page) - Content Encoding Error / Error 330 (net::ERR_CONTENT_DECODING_FAILED): Unknown error.

when I'm trying to open the page that not exists, for example:

http://test.pro-okr.nazwa.pl/fsdfsdfsdfsdfsdf
http://test.pro-okr.nazwa.pl/sdfsdfsdf
http://test.pro-okr.nazwa.pl/4543lrtldgkdf


I get strange error. Different in all of major browsers. The most enigmatic in opera. What can I do?

I'm using the newest version of MODx Revo. [ed. note: quardas last edited this post 14 years, 3 months ago.]

Solution:
Put this code to .htaccess and everything will be fine.

SetEnv force-no-vary
SetEnv downgrade-1.0

Thanks to Bogdan Khorolets for this solution.

Thanks! It really helps

Just to make picture fuller. Another solution is to create two system parameters:

• error_page_header (Name: "HTTP header for 404", Value: "HTTP/1.0 404 Not Found", Type: text, Namespace: core, Lang string: site)
• unauthorized_page_header: (Name: "HTTP header for 403", Value: "HTTP/1.0 403 Forbidden", Type: text, Namespace: core, Lang string: site)

I think this solution is more flexible since it changes headers only for 404 and 403 statuses.

According to this post (in Russian), the problem occures on hostings with Apache+Nginx. MODX Revo sends all the headers as HTTP/1.1, and Nginx gives HTTP/1.0 to Apache. So, Apache tries to respond to HTTP/1.0 with HTTP/1.1, mocks it up and adds chunks to headers, which is treated as errors by Nginx.

Thanks to Viktor Dolgy fo the solution and the explaination.
