Hi guys,

I have done nothing, but my RSS feed has suddenly stopped working... I usually send it to my readers weekly. Last week it was fine, but this week it isn't.

Here is what the validator says:
http://validator.w3.org/feed/check.cgi?u...limit%3D15

the feed is this one:
http://www.autosvezzamento.it/forum/synd...7&limit=15

I would like to stress that it has been working fine for months and months and I have not done anything to it nor have I updated anything or added plugins.

Any clues?

TIA

UPDATE
If I try

http://www.autosvezzamento.it/forum/synd...7&limit=15
that works fine... (that is a different feed I use to list all the latest posts (not threads) on my blog)

The feed seemed to work briefly, but now I am back to square one.

Is there anyone who knows something about RRS feeds?
