We've run into a snag using AA Pro to show multiple related articles on many pages of our site.

The code for displaying related articles in a content module is rather simple - like this:

This is what happens:

- After clearing cache and loading the page for the first time, the selection of articles is fine and limited according to above rule.
- On second load, the module display a 'super-set', meaning more articles than it should. It appears the filtering is not working, and it pulls a cached (generic) version. Could it be it's ignoring the tags?

- Trying different types of caching levels (file, memcached, conservative, progressive) but the issue remains.

- Contrary, when caching is disabled, everything works fine.

Is this a known issue or is there something else we could try.

Hi Peter,

I tried your suggestion and turned caching off at the content module level. Then turned server caching on (File - conservative). The issue remains: It would show the 'super-set' on second load.

Also, it's not like it showing the results from A when on B. It's showing all results from category '53' and ignores the tags in the filtering hence the result list is longer on second load.

P.S. I should add that I'm using AA Pro in combination with Advanced Module Manager, but I assume that shouldn't have a bearing on this issue.

Thanks Peter. Still doesn't work. I tried with different caching scenarios. I will try a few other scenarios also with AMM disabled etc. See if that makes a difference.

Here is a link to a page that's rarely used.
Look at the right hand side (on desktop) you should see 'Referenced articles' with one entry.

After reloading the page it will show >10.

As for super admin let me get back to you on that as I was playing around on our staging right now.

This is what I found after further investigation:

- The caching issue appears only when the AA code is included in a Joomla content module (mod_custom). When the AA code gets included directly in an article, there is no problem with caching.
- The caching issue also appears, when I tried using the standard Joomla Cassiopeia template (as I was suspicious whether it could be the Gantry framework I am using). So the framework is not causing it.
- Trying different caching scenarios (Conservative, Progressive and with File versus Memcached) all results in the same issue.

- I also checked the cache and found that
-- On initial load of the page, the correct AA content got placed into the cache
-- On re-loading the same page in the browser, another version of the AA content got placed into the cache and shown, this time with the 'tags' filter and the 'limit' filter ignored.

It's like on re-loading the page, the cached regularlabs AA snippet cannot be found, hence creating another version but in doing so the article's tags get ignored within {articles categories="53" tags="current" ordering="title" limit="10"} as well as the limit.

I realize that this is probably a very rare scenario, could be server related, could be AA related, heck - could be even mod_custom related.

Appreciate any thoughts/ideas where else to look & test.

Hi Peter, I had to prepare this a little bit for you to make this hopefully as simple as possible to trace down.

I created a clone of the site and it behaves in the same way with the same issue.

Find more details in the Confidential section. Really curious what you will find.

SiteGround it is. I had set caching to file to circumvent memcache. I also deactivated memcache overall on the account just to make sure nothing is interfering (although Joomla should handle that itself anyhow). Also, static files are running through NGinX - but again never had issues with that in J3+AA so I would be ruling out that as a source for this issue.

On another note: I tried the infamous 'Content Prepare' Option yesterday for the content modules. No surprise there: After the content module was called for the first time, subsequently it always showed the same content (when caching was turned on).

That - of course - isn't helpful as the content modules are dynamic and page-specific. Thought I should mention it here.

I had a bad feeling about this when I contacted them and learned that the cache cleaning plugin they had offered was no longer available on J4. Thanks for looking into this Peter, really appreciate it - your plugins and components are awesome!

Yeah - we need a host with servers in North America.

If anyone on this forum has had a good experience with a J4 hosting provider in North America, please post here.

You can try A2Hosting. It's not perfect, but it's better than many.
