Hello,
I have made a rss version 2.0 document. I believe it's a completely fine XML file, since I can parse and show it on browser using PHP by pointing to the address in which it's located. Even when I visit my page I can see RSS button on firefox address bar and when I click on it, I can see rss content and I can subscribe to it. But my problem is that when I subscribe to it, it doesn't show anything even when I reload it.

I just tried to subscribe to it using Thunderbird. In Thunderbird I can receive all subjects and links, but I can't see anything related to description. I have to mention that the text inside title and description tags are in Farsi and I don't use any special function to convert it to UTF8 since the data coming to it is from mysql table with charset=utf8.

I can't figure out what's wrong with it. since everything seems to be correct.

Any suggestion?

Are all html tags inside the <description> tags escaped properly, ie:

Perhaps you need to post the XML (or perhaps better, a link to it).

xml file is located at http://www.havadarha.com/xml/news.xml

I just found out that it works in thunderbird very fine. I even can see all description.

Basically there's no html tag inside description.
