   HI there. I frequently have problems with my RSS feed being out of date. Could this be related to w3 caching the feed? Is it supposed to cache the feed?

   Thanks!

   Okay, verified. This thing is definitely caching my RSS feed and it's not getting updated unless I manually clear the cache. What would cause this?

   Under Page Cache you might want to try these settings:

   Never cache the following pages:
   wp-.*
   .php
   index.php
   like.php
   *.xml
   *.rss

   Ahh... cool. Let me try that.

   Should I also put:

   http://www.my-site.com/feed/ ?

   Or is that a fake URL?

   Are you sure it's a good idea to have "index.php" in there? Wouldn't I want that to cache?

   HOLY $*(#@($@#*

   Messing with that just 500 error'd my entire site. I'm dead in the water. Can't even log in. WTF with this plugin?

   I'll report back ...

   Wow... that was a horrible 30 minutes.

   Thank god I know how to FTP in and mess with the htaccess file. Apparently simply adding these two lines to the "do not cache" list:

   *.xml
   *.rss

   Completely killed everything. Total 500 error loss. The only way forward was to delete htaccess and rebuild. If I were a novice at this stuff I could have been down for days. W3 cache guys seriously need to know about this. Will email them now...

   Oops, sorry to hear that. These settings were the default when I installed w3ctc and they've done nicely for the last year and still.

   But error 500s seem to be another feature of this plugin. I get them quite frequently.

   Ha! that's definitely not good... I've let them know. A novice user could be seriously up the creek if that happens.

   I was following this thread and exactly the same thing happened to my site when I added:

   *.xml
   *.rss

   500 Internal server error, and as a novice I was seriously up the creek. Fortunately my hosting provider is one of the best in the business for service and they fixed my .htaccess for me.

   So, unless you know what you are doing, be careful adding those settings to "never cache the following pages"

   There already is a setting in the current version of W3TC for caching/not caching feeds, so I'm wondering if adding this to the "never cache" causes a conflict.

    I came to these forums to finally report this problem, too. Are we all running WordPress 3.3? This RSS caching issue showed up after I upgraded.

    I'm running WordPress Network. Anyone else?

    I've had to force refresh my cache whenever I publish a new post. It's terrible. And I've had the same settings that I had in WP 3.2.

    W3TC just may not be compatible with WP 3.3 yet.

    Yeah.... I have latest wordpress. The caching problem seems to have gone away. No idea how. Your still batty?

    I can't quite tell. I forgot to check when I published a new post, but it did show up in the RSS feed overnight. But I also think I remember refreshing my cache anyway after moving a widget (which doesn't always refresh that cache on its own).

    It could be that W3TC is being very slow at updating the RSS cache.

    Well, I can tell. I posted two podcast episodes yesterday, each to a separate site on my WordPress 3.3.1 Network. On one site, I had to refresh the cache to remove the widget. That site's episode was available in the RSS feed.

    But on the other site, where I actually posted first around 10:30 last night, the feed still wasn't updated nearly twelve hours later!

    This is unacceptable, and it's a waste of the cache to have to refresh it every time I post something new. So I'm going to switch to WP Super Cache.

    Well, I haven't noticed any RSS problems with my sites so far. But there is one thing that should be eyed with suspicion: Total Cache always writes to the main htaccess in the root directory. That is OK as long as you a running a single side or a multisite with clones of the main site. But this might cause a problem or two when you are trying to entertain a blog garden with many different flowers, plugins, scripts, whatnots and individual settings.

    I find it rather sad, though, that there hasn't been an update for half a year or so, because the idea of Total Cache is really neat.

    Part of the issue is with garbage collection. Working on increasing reliability here.
