We are using the default feed display module in Joomla 1.6.3 to display 2 news feed from google.
When we however turn on the caching under global options these feeds will only display on the first page (menu item) that gets generated, any other pages/menus will have these module positions show as empty.

We tried memcache and file cache and neither works. Disabling the module cache itself has no effect either.

To issue is visible on http://www.socialcrm.nl and then on the bottom of the page are 3 module positions (QR code / feed / feed) the feeds will show up on the frontpage but not on other pages/menu items.

Does anyone have any idea on how to resolve this?

I am also experiencing a caching problem with Joomla 1.6.3.

Whenever I turn on the caching under the global options to either conservative caching or progessive caching, some of my column widths on content pages stick. What I mean by this is if the left column displays on one content page and not the next, a blank space appears where the left column was on the previous page.

The only way to get things to display properly after clearing all server and browser cache is to leave caching disabled under the global configuration settings. I would appreciate any help with this issue as well.

Thanks,
Matt

The problem seems to persist, and i believe i've exhausted all caching options.
Whether it's file or memcache, progressive or conservative caching the feed display module will be empty at some point. The only solution to get the feed to display again is clearing out the cache manually.

Any insight or help would be greatly appreciated.

Read http://joomla-extensions.kubik-rubik.de ... omla-cache - this seems to work:
Code:
// Clean Cache
$cache = JFactory::getCache();
$cache->clean();      
$cache->remove($cache->makeId(), 'page');

I've used it on http://starthilfeberlin.de/ in mod_feed.php, right before:
Code:
$feed = modFeedHelper::getFeed($params);

But I suggest this can be solved in a better way...

jazzvox thank you very much for the idea, however this does not seem to do anything for me.
I am however looking further into doing something to the cache so that it will not cache or interfere with the RSS Feeds i am displaying on our site.

This will do it:
Quote:
// FIX! Clean Cache
$cache = JFactory::getCache('feed_parser');
$cache->clean();

Upload your own default.php > /templates/yours/html/mod_feed/
to overwrite the core template as usual, and put this right after:
Code:
if ($feed != false)
{
....

Took me some effort to find out WHERE the data is stored.

The fortune is that this way all other cache files will not be touched ;-)

I found a solution for this issue which works for me...
You can fix it by changing line 501 in libraries/joomla/cache/cache.php from

Code:
if ($loptions['nohead'] != 1) {



to

Code:
 if ($loptions['nohead'] != 1 && method_exists($document, 'getHeadData')) {

Wondered if anyone has tracked this down? I'd like to have real working cache for the feed!

Thanks.

OK, so this looks like a good track, but I find different code at line #501,
instead of :
Code:
if ($loptions['nohead'] != 1) {


What I see is:
Code:
 if (isset($options['nohead'])) {
.

Probably the right place still, but is this relevant to V1.7.3?

Thanks!

Charlie

The line of code mentioned above is down at about 529 for Joomla 1.7.3.

Alas, it still doesn't solve my disappearing module feeds.

I am using joomla 1.7.3 and the same thing happens to me with an admin feed display module. I linked in the security news feed and when cache is enabled the feed displays initially until I move away from the control panel. Once I navigate back the text from the feed no longer shows. Sometimes the text from the feed comes back when I log in later but the same thing happens once I navigate away from the cpanel to do something then come back. If cache is disabled then it works. I tried disabled caching of the feed display module (in advanced options on the module) and that didn't work. I discovered once I delete the feed_parser directory and all its files the feed text displayed (in the /httpdocs/administrator/cache directory).

I used the code:
// FIX! Clean Cache
$cache = JFactory::getCache('feed_parser');
$cache->clean();

I put this in the file: /httpdocs/administrator/modules/mod_feed/mod_feed.php
above this line:
//check if cache diretory is writable as cache files will be created for the feed

I assume this code just deletes the feed_parser cache like I did manually in ftp.
Not sure if this is a bug or something I did on my end, but the text seems to show.

Thanks, Nate! I'll give it a try.

Update: This seems to have fixed my podcast manager feed, but the feed display modules still go blank on refresh.

Bump. Still a problem after the 2.5 update. I found a related thread that suggested removing odd characters (&, -, and / in my case) from the meta data, but no dice.

Alright, I think I know what happens. I don't know why it happens or how to fix it, but maybe this description of the problem will help.

What happens is that two different cached blobs are involved. When trying to get the information, a check is made for it at cache/feed_parser/xxxxxx.php and the result is extracted from that file if it exists. If it does not exist, then a connection is made to the feed and the result is stored in a different place, namely at cache/mod_feed/yyyyyy.php so that it is not found next time. This would be just an inconvenience were it not because the first file (the one at cache/feed_parser) is created too, but without the right content. I my case, it holds:
Code:
<?php die("Access Denied"); ?>#x#a:2:{s:6:"output";s:0:"";s:6:"result";b:1;}

I.e. result just contains a boolean true value instead of what it should contain.

Thanks for that. My feed_parser file contains the same, though I don't have the mod_feed directory at all.

I'm still frustrated by this problem. I'd have thought that after 7 minor version updates the problem would have been resolved. I tried today on 2.5.3, and the problem still occurs.

Now seems working.

I completely disable the Joomla system cache (in configuration.php and plugins), installed components Jotcache.

All seems working on all browsers.

We dont talk about the system-cache-plugin. It's the global system cache, which doesnt work with the rss-feed-module...

Version 2.5.6 and this is still broken. Very disappointing as I have many sites that use RSS modules (or would... I've had to disable them all). I'd hate to have to implement fgrasso's solution on all of them.

Developers, any feedback on this at all?

Same here. Rss-feed-module is useless when cache is on. Without caching it's slow. J! 2.5.6 and still no solution.

Same for me with the built-in RSS news feed extension (not module) for J! 2.5.6
When clearing the cache, it works, but blank pages are generated afterwards, when coming back on those news feed pages. I'm checking if this has been reported as a bug, and if not, report it.
Very annoying.

For those of you having problems with caching of RSS feeds, please try enabling both of the following:

1. Global Configuration > System > Cache Settings > On
2. Extensions > Plug-in Manager > System - Cache > Status: Enabled

Doing so works on my site with RSS feeds on the home page.

For those of you with systems administration access, I use APC for server-side caching. You shouldn't see this option in Joomla's caching settings unless APC is installed.

I'm almost certain that the system cache plugin was always enabled, but I just tried it again (2.5.7) and my feeds disappeared on reload. I'm using JotCache per an earlier suggestion with good results.

I am still having this issue across multiple sites with 2.5.7. It would be really great if this issue could be resolved as soon as possible - the fixes here seem to work but it would be even better if the system plugins would work.
